Find LCM of 763,671,594,442,420 with Prime Factorization
| 2 | 763, 671, 594, 442, 420 |
| 3 | 763, 671, 297, 221, 210 |
| 7 | 763, 671, 99, 221, 70 |
| 11 | 109, 671, 99, 221, 10 |
| 109, 61, 9, 221, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 109 x 61 x 9 x 221 x 10 = 61098857820
Therefore, the lowest common multiple of 763,671,594,442,420 is 61098857820.
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.
763 x 671 x 594 x 442 x 420 = 56455344625680
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.
763 : 1, 7, 109, 763
671 : 1, 11, 61, 671
594 : 1, 2, 3, 6, 9, 11, 18, 22, 27, 33, 54, 66, 99, 198, 297, 594
442 : 1, 2, 13, 17, 26, 34, 221, 442
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,671,594,442,420, is 1.
Now, the common factors can be found like this.
763:7x 109
671:11x 61
594:2x 3x 3x 3x 11
442:2x 13x 17
420:2x 2x 3x 5x 7
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 3x 7x 11 = 924
Therefore, the value for common factors is 924.
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 = 56455344625680/(1x924)
LCM = 56455344625680/924
LCM = 61098857820
Thus, we can understand that the LCM of 763,671,594,442,420 is 61098857820.
