Given numbers are 533,676,780,818
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 533,676,780,818 is 170037660.
Find LCM of 533,676,780,818 with Prime Factorization
| 2 | 533, 676, 780, 818 |
| 2 | 533, 338, 390, 409 |
| 13 | 533, 169, 195, 409 |
| 41, 13, 15, 409 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 41 x 13 x 15 x 409 = 170037660
Therefore, the lowest common multiple of 533,676,780,818 is 170037660.
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.
533 x 676 x 780 x 818 = 229890916320
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.
533 : 1, 13, 41, 533
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
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
818 : 1, 2, 409, 818
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 533,676,780,818, is 1.
Now, the common factors can be found like this.
533:13x 41
676:2x 2x 13x 13
780:2x 2x 3x 5x 13
818:2x 409
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 13x 13 = 1352
Therefore, the value for common factors is 1352.
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 = 229890916320/(1x1352)
LCM = 229890916320/1352
LCM = 170037660
Thus, we can understand that the LCM of 533,676,780,818 is 170037660.
