Find LCM of 624,671,748,871 with Prime Factorization
| 2 | 624, 671, 748, 871 |
| 2 | 312, 671, 374, 871 |
| 11 | 156, 671, 187, 871 |
| 13 | 156, 61, 17, 871 |
| 12, 61, 17, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 13 x 12 x 61 x 17 x 67 = 476903856
Therefore, the lowest common multiple of 624,671,748,871 is 476903856.
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 671 x 748 x 871 = 272789005632
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
671 : 1, 11, 61, 671
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,671,748,871, is 1.
Now, the common factors can be found like this.
624:2x 2x 2x 2x 3x 13
671:11x 61
748:2x 2x 11x 17
871:13x 67
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 11x 13 = 572
Therefore, the value for common factors is 572.
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 = 272789005632/(1x572)
LCM = 272789005632/572
LCM = 476903856
Thus, we can understand that the LCM of 624,671,748,871 is 476903856.
