60 and 120
3, 5 and 6 are factors of 30
The number 40 is a multiple of both 4 and 5.
Numbers without factors are PRIME Numbers. Taking the first ten numbers. 1,2,3,4,5,6,7,8,9,10. The prime numbers are 2,3,5,7, they have no factors. 4,6,8,9,10. Are not prime numbers as they have factors. 4 has a factor of '2' 6 has factors of '2 & 3'. 8 has factors of' 2 & 4'. or' 2,2,2.' 9 has factors of '3,3', 10 has factors of '2 5.' '1' is unique
As a product of its prime factors: 2 * 2 * 5 * 5 = 100
