Find LCM of 705,542,572,678,480 with Prime Factorization
| 2 | 705, 542, 572, 678, 480 |
| 2 | 705, 271, 286, 339, 240 |
| 3 | 705, 271, 143, 339, 120 |
| 5 | 235, 271, 143, 113, 40 |
| 47, 271, 143, 113, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 47 x 271 x 143 x 113 x 8 = 98792247840
Therefore, the lowest common multiple of 705,542,572,678,480 is 98792247840.
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.
705 x 542 x 572 x 678 x 480 = 71130418444800
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
542 : 1, 2, 271, 542
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
678 : 1, 2, 3, 6, 113, 226, 339, 678
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,542,572,678,480, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
542:2x 271
572:2x 2x 11x 13
678:2x 3x 113
480:2x 2x 2x 2x 2x 3x 5
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 2x 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 71130418444800/(1x720)
LCM = 71130418444800/720
LCM = 98792247840
Thus, we can understand that the LCM of 705,542,572,678,480 is 98792247840.
