The LCM of 872,715,478,572 is 149011720.
Find LCM of 872,715,478,572 with Prime Factorization
| 2 | 872, 715, 478, 572 |
| 2 | 436, 715, 239, 286 |
| 11 | 218, 715, 239, 143 |
| 13 | 218, 65, 239, 13 |
| 218, 5, 239, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 13 x 218 x 5 x 239 x 1 = 149011720
Therefore, the lowest common multiple of 872,715,478,572 is 149011720.
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.
872 x 715 x 478 x 572 = 170469407680
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.
872 : 1, 2, 4, 8, 109, 218, 436, 872
715 : 1, 5, 11, 13, 55, 65, 143, 715
478 : 1, 2, 239, 478
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,715,478,572, is 1.
Now, the common factors can be found like this.
872:2x 2x 2x 109
715:5x 11x 13
478:2x 239
572:2x 2x 11x 13
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 11x 13 = 1144
Therefore, the value for common factors is 1144.
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 = 170469407680/(1x1144)
LCM = 170469407680/1144
LCM = 149011720
Thus, we can understand that the LCM of 872,715,478,572 is 149011720.
