Given numbers are 530,637,605,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 530,637,605,418 is 776165390.
Find LCM of 530,637,605,418 with Prime Factorization
| 2 | 530, 637, 605, 418 |
| 5 | 265, 637, 605, 209 |
| 11 | 53, 637, 121, 209 |
| 53, 637, 11, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 53 x 637 x 11 x 19 = 776165390
Therefore, the lowest common multiple of 530,637,605,418 is 776165390.
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.
530 x 637 x 605 x 418 = 85378192900
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.
530 : 1, 2, 5, 10, 53, 106, 265, 530
637 : 1, 7, 13, 49, 91, 637
605 : 1, 5, 11, 55, 121, 605
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 530,637,605,418, is 1.
Now, the common factors can be found like this.
530:2x 5x 53
637:7x 7x 13
605:5x 11x 11
418:2x 11x 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 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 85378192900/(1x110)
LCM = 85378192900/110
LCM = 776165390
Thus, we can understand that the LCM of 530,637,605,418 is 776165390.
