Find LCM of 624,715,784,852 with Prime Factorization
| 2 | 624, 715, 784, 852 |
| 2 | 312, 715, 392, 426 |
| 2 | 156, 715, 196, 213 |
| 2 | 78, 715, 98, 213 |
| 3 | 39, 715, 49, 213 |
| 13 | 13, 715, 49, 71 |
| 1, 55, 49, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 13 x 1 x 55 x 49 x 71 = 119399280
Therefore, the lowest common multiple of 624,715,784,852 is 119399280.
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 715 x 784 x 852 = 298020602880
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
715 : 1, 5, 11, 13, 55, 65, 143, 715
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,715,784,852, is 1.
Now, the common factors can be found like this.
624:2x 2x 2x 2x 3x 13
715:5x 11x 13
784:2x 2x 2x 2x 7x 7
852:2x 2x 3x 71
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 2x 3x 13 = 2496
Therefore, the value for common factors is 2496.
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 = 298020602880/(1x2496)
LCM = 298020602880/2496
LCM = 119399280
Thus, we can understand that the LCM of 624,715,784,852 is 119399280.
