Two.
As a product of its prime factors: 2*61 = 122
38 = 2 X 19
As a product of its prime factors: 5*7*11 = 385
As a product of its prime factors: 2*2*5*5 = 100
Factor the numbers into primes: 55 = 5 * 11 143 = 13 * 11 110 = 2 * 5 * 11 The ONLY factor they all have in common is 11. 11 is the greatest (and only) common factor.
As a product of its prime factors in exponents: 2^3 times 5^2 = 200
48 = 2 × 2 × 2 × 2 × 3
There are no two primes whose product is 50.There are no two primes whose product is 50.There are no two primes whose product is 50.There are no two primes whose product is 50.
The prime factors of 70 are 2,5 and 7 so their product is 70. This will happen whenever the prime factors occur only once. When we factor 70 into primes, we are asking for those primes who product is equal to 70. However, sometimes we get one or more primes raise to a power in the prime factorization. In this case, the prime raised to a power is no longer a prime so the product of prime factors is less than the number.
102 = 2*3*17
The products of the primes are the composites.
