Find LCM of 460,391,584,649,620 with Prime Factorization
| 2 | 460, 391, 584, 649, 620 |
| 2 | 230, 391, 292, 649, 310 |
| 5 | 115, 391, 146, 649, 155 |
| 23 | 23, 391, 146, 649, 31 |
| 1, 17, 146, 649, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 1 x 17 x 146 x 649 x 31 = 22970264680
Therefore, the lowest common multiple of 460,391,584,649,620 is 22970264680.
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.
460 x 391 x 584 x 649 x 620 = 42265287011200
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.
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
391 : 1, 17, 23, 391
584 : 1, 2, 4, 8, 73, 146, 292, 584
649 : 1, 11, 59, 649
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 460,391,584,649,620, is 1.
Now, the common factors can be found like this.
460:2x 2x 5x 23
391:17x 23
584:2x 2x 2x 73
649:11x 59
620:2x 2x 5x 31
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 2x 5x 23 = 1840
Therefore, the value for common factors is 1840.
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 = 42265287011200/(1x1840)
LCM = 42265287011200/1840
LCM = 22970264680
Thus, we can understand that the LCM of 460,391,584,649,620 is 22970264680.
