Given numbers are 662,557,780,490,534
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 662,557,780,490,534 is 627139099860.
Find LCM of 662,557,780,490,534 with Prime Factorization
| 2 | 662, 557, 780, 490, 534 |
| 3 | 331, 557, 390, 245, 267 |
| 5 | 331, 557, 130, 245, 89 |
| 331, 557, 26, 49, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 331 x 557 x 26 x 49 x 89 = 627139099860
Therefore, the lowest common multiple of 662,557,780,490,534 is 627139099860.
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.
662 x 557 x 780 x 490 x 534 = 75256691983200
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.
662 : 1, 2, 331, 662
557 : 1, 557
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
534 : 1, 2, 3, 6, 89, 178, 267, 534
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,557,780,490,534, is 1.
Now, the common factors can be found like this.
662:2x 331
557:557
780:2x 2x 3x 5x 13
490:2x 5x 7x 7
534:2x 3x 89
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 75256691983200/(1x120)
LCM = 75256691983200/120
LCM = 627139099860
Thus, we can understand that the LCM of 662,557,780,490,534 is 627139099860.
