Find LCM of 420,777,666,767,832 with Prime Factorization
| 2 | 420, 777, 666, 767, 832 |
| 2 | 210, 777, 333, 767, 416 |
| 3 | 105, 777, 333, 767, 208 |
| 7 | 35, 259, 111, 767, 208 |
| 13 | 5, 37, 111, 767, 208 |
| 37 | 5, 37, 111, 59, 16 |
| 5, 1, 3, 59, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 13 x 37 x 5 x 1 x 3 x 59 x 16 = 572120640
Therefore, the lowest common multiple of 420,777,666,767,832 is 572120640.
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.
420 x 777 x 666 x 767 x 832 = 138695774031360
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.
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
777 : 1, 3, 7, 21, 37, 111, 259, 777
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
767 : 1, 13, 59, 767
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,777,666,767,832, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
777:3x 7x 37
666:2x 3x 3x 37
767:13x 59
832:2x 2x 2x 2x 2x 2x 13
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 3x 7x 13x 37 = 242424
Therefore, the value for common factors is 242424.
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 = 138695774031360/(1x242424)
LCM = 138695774031360/242424
LCM = 572120640
Thus, we can understand that the LCM of 420,777,666,767,832 is 572120640.
