Find LCM of 624,784,974,957 with Prime Factorization
| 2 | 624, 784, 974, 957 |
| 2 | 312, 392, 487, 957 |
| 2 | 156, 196, 487, 957 |
| 2 | 78, 98, 487, 957 |
| 3 | 39, 49, 487, 957 |
| 13, 49, 487, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 13 x 49 x 487 x 319 = 4750073328
Therefore, the lowest common multiple of 624,784,974,957 is 4750073328.
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.
624 x 784 x 974 x 957 = 456007039488
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.
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
974 : 1, 2, 487, 974
957 : 1, 3, 11, 29, 33, 87, 319, 957
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,784,974,957, is 1.
Now, the common factors can be found like this.
624:2x 2x 2x 2x 3x 13
784:2x 2x 2x 2x 7x 7
974:2x 487
957:3x 11x 29
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 2x 2x 3 = 96
Therefore, the value for common factors is 96.
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 = 456007039488/(1x96)
LCM = 456007039488/96
LCM = 4750073328
Thus, we can understand that the LCM of 624,784,974,957 is 4750073328.
