140 = 2 x 2 x 5 x 7
It is 7 because as a product of its prime factors: 2*2*5*7 = 140 or as 22*5*7 = 140
22 • 5 • 7 = 140
2 x 2 x 5 x 7 = 140
2 x 2 x 5 x 7 = 140
The factorization of 140 can be expressed as the product of its prime factors. It can be factored as ( 140 = 2^2 \times 5 \times 7 ). This means that 140 is made up of the prime numbers 2, 5, and 7, with 2 appearing twice.
Prime factorization is the finding which prime number multiply to get to make the original number. 140: 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140 Prime: 2, 5, 7 Prime Factorization: 2 x 2 x 5 x 7
