Given numbers are 680,646,493,583
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 680,646,493,583 is 218438440.
Find LCM of 680,646,493,583 with Prime Factorization
| 2 | 680, 646, 493, 583 |
| 17 | 340, 323, 493, 583 |
| 20, 19, 29, 583 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 20 x 19 x 29 x 583 = 218438440
Therefore, the lowest common multiple of 680,646,493,583 is 218438440.
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.
680 x 646 x 493 x 583 = 126257418320
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.
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
646 : 1, 2, 17, 19, 34, 38, 323, 646
493 : 1, 17, 29, 493
583 : 1, 11, 53, 583
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,646,493,583, is 1.
Now, the common factors can be found like this.
680:2x 2x 2x 5x 17
646:2x 17x 19
493:17x 29
583:11x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 17 = 578
Therefore, the value for common factors is 578.
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 = 126257418320/(1x578)
LCM = 126257418320/578
LCM = 218438440
Thus, we can understand that the LCM of 680,646,493,583 is 218438440.
