Find LCM of 630,671,435,657,220 with Prime Factorization
| 2 | 630, 671, 435, 657, 220 |
| 3 | 315, 671, 435, 657, 110 |
| 3 | 105, 671, 145, 219, 110 |
| 5 | 35, 671, 145, 73, 110 |
| 11 | 7, 671, 29, 73, 22 |
| 7, 61, 29, 73, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 7 x 61 x 29 x 73 x 2 = 1789838820
Therefore, the lowest common multiple of 630,671,435,657,220 is 1789838820.
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.
630 x 671 x 435 x 657 x 220 = 26579106477000
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
671 : 1, 11, 61, 671
435 : 1, 3, 5, 15, 29, 87, 145, 435
657 : 1, 3, 9, 73, 219, 657
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,671,435,657,220, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
671:11x 61
435:3x 5x 29
657:3x 3x 73
220:2x 2x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5x 5x 11 = 14850
Therefore, the value for common factors is 14850.
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 = 26579106477000/(1x14850)
LCM = 26579106477000/14850
LCM = 1789838820
Thus, we can understand that the LCM of 630,671,435,657,220 is 1789838820.
