Find LCM of 762,780,666,351,531 with Prime Factorization
| 2 | 762, 780, 666, 351, 531 |
| 3 | 381, 390, 333, 351, 531 |
| 3 | 127, 130, 111, 117, 177 |
| 13 | 127, 130, 37, 39, 59 |
| 127, 10, 37, 3, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 13 x 127 x 10 x 37 x 3 x 59 = 1946231820
Therefore, the lowest common multiple of 762,780,666,351,531 is 1946231820.
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.
762 x 780 x 666 x 351 x 531 = 73777755832560
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.
762 : 1, 2, 3, 6, 127, 254, 381, 762
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
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
351 : 1, 3, 9, 13, 27, 39, 117, 351
531 : 1, 3, 9, 59, 177, 531
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,780,666,351,531, is 3.
Now, the common factors can be found like this.
762:2x 3x 127
780:2x 2x 3x 5x 13
666:2x 3x 3x 37
351:3x 3x 3x 13
531:3x 3x 59
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 3x 3x 3x 3x 3x 13 = 12636
Therefore, the value for common factors is 12636.
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 = 73777755832560/(3x12636)
LCM = 73777755832560/37908
LCM = 1946231820
Thus, we can understand that the LCM of 762,780,666,351,531 is 1946231820.
