Its factorization makes it a sphenic number. In Mathematics, factorization ( also factorisation in British English) or factoring is the decomposition of an object (for In Mathematics, a sphenic number ( Old Greek sphen = Wedge) is a positive integer which is the product of three distinct Prime 70 is a Pell number and a generalized heptagonal number, one of only two numbers to be both. In Mathematics, the Pell numbers and companion Pell numbers (Pell-Lucas numbers are both sequences of Integers that have been known since ancient A heptagonal number is a Figurate number that represents a Heptagon. [1] Also, it is the seventh pentagonal number and the fourth 13-gonal number, as well as the fifth pentatope number. A pentagonal number is a Figurate number that extends the concept of triangular and Square numbers to the Pentagon, but unlike the first A pentatope number is a number in the fifth cell of any row of Pascal's triangle starting with the 5-term row 1 4 6 4 1 either from left to right or from right to left It is the smallest weird number. In Mathematics, a weird number is a Natural number that is abundant but not semiperfect.

Since it is possible to find sequences of 70 consecutive integers such that each inner member member shares a factor with either the first or the last member, 70 is an Erdős–Woods number. Consider a sequence of consecutive Positive integers a+1 \dots a+k

In base 10, it is a Harshad number. The decimal ( base ten or occasionally denary) Numeral system has ten as its base. A Harshad number, or Niven number, is an Integer that is divisible by the sum of its digits in a given number base.
