The LCM of 644,829,157,506,956 is 220358920628.
Find LCM of 644,829,157,506,956 with Prime Factorization
| 2 | 644, 829, 157, 506, 956 |
| 2 | 322, 829, 157, 253, 478 |
| 23 | 161, 829, 157, 253, 239 |
| 7, 829, 157, 11, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 7 x 829 x 157 x 11 x 239 = 220358920628
Therefore, the lowest common multiple of 644,829,157,506,956 is 220358920628.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
644 x 829 x 157 x 506 x 956 = 40546041395552
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
829 : 1, 829
157 : 1, 157
506 : 1, 2, 11, 22, 23, 46, 253, 506
956 : 1, 2, 4, 239, 478, 956
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,829,157,506,956, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
829:829
157:157
506:2x 11x 23
956:2x 2x 239
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 23 = 184
Therefore, the value for common factors is 184.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 40546041395552/(1x184)
LCM = 40546041395552/184
LCM = 220358920628
Thus, we can understand that the LCM of 644,829,157,506,956 is 220358920628.
