Find LCM of 637,877,988,478,931 with Prime Factorization
| 2 | 637, 877, 988, 478, 931 |
| 7 | 637, 877, 494, 239, 931 |
| 7 | 91, 877, 494, 239, 133 |
| 13 | 13, 877, 494, 239, 19 |
| 19 | 1, 877, 38, 239, 19 |
| 1, 877, 2, 239, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 13 x 19 x 1 x 877 x 2 x 239 x 1 = 10147300436
Therefore, the lowest common multiple of 637,877,988,478,931 is 10147300436.
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.
637 x 877 x 988 x 478 x 931 = 245625554353816
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.
637 : 1, 7, 13, 49, 91, 637
877 : 1, 877
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
478 : 1, 2, 239, 478
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,877,988,478,931, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
877:877
988:2x 2x 13x 19
478:2x 239
931:7x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 13x 19 = 24206
Therefore, the value for common factors is 24206.
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 = 245625554353816/(1x24206)
LCM = 245625554353816/24206
LCM = 10147300436
Thus, we can understand that the LCM of 637,877,988,478,931 is 10147300436.
