It's not necessary. Since 30 is a multiple of 10, it's automatically the LCM, but if you insist...
2 x 5 = 10
2 x 3 x 5 = 30
Combine the factors, eliminating duplicates.
2 x 3 x 5 = 30, the LCM
10 squared times 2squared
2 x 5 = 10 5 x 5 = 25 The GCF is 5.
Prime factorization:10 = 2 x 518 = 2 x 3245 = 5 x 322 x 5 x 32 = 90 (the LCM of 10, 18, and 45)
Find the numbers that include others in their prime factorization: 7, 9, and 10 Multiply them: 630
2 x 3 = 6 2 x 5 = 10 The GCF is 2.
10 2,5
1.0*10^1
10 = 21*51
20 / 2 = 10 10 / 2 = 5 so prime factorization is 2 x 2 x 5
10 to the third power
The prime factorization of 10 is 2 x 5. You need another number to find a GCF or LCM.
2 x 5 = 10 2 x 2 x 7 = 28 Combine the factors, eliminating duplicates. 2 x 2 x 5 x 7 = 140, the LCM
10 squared times 2squared
Visualize the prime factorization of 10. (2 x 5) Since 10,000 is 104, the prime factorization of 10,000 will be 24 x 54.
2 x 5 = 10 5 x 5 = 25 The GCF is 5.
It is: 30
Prime factorization:10 = 2 x 518 = 2 x 3245 = 5 x 322 x 5 x 32 = 90 (the LCM of 10, 18, and 45)
