Given numbers are 624,580,779,328
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 624,580,779,328 is 70483920.
Find LCM of 624,580,779,328 with Prime Factorization
| 2 | 624, 580, 779, 328 |
| 2 | 312, 290, 779, 164 |
| 2 | 156, 145, 779, 82 |
| 41 | 78, 145, 779, 41 |
| 78, 145, 19, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 41 x 78 x 145 x 19 x 1 = 70483920
Therefore, the lowest common multiple of 624,580,779,328 is 70483920.
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.
624 x 580 x 779 x 328 = 92474903040
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.
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
779 : 1, 19, 41, 779
328 : 1, 2, 4, 8, 41, 82, 164, 328
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,580,779,328, is 1.
Now, the common factors can be found like this.
624:2x 2x 2x 2x 3x 13
580:2x 2x 5x 29
779:19x 41
328:2x 2x 2x 41
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 2x 41 = 1312
Therefore, the value for common factors is 1312.
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 = 92474903040/(1x1312)
LCM = 92474903040/1312
LCM = 70483920
Thus, we can understand that the LCM of 624,580,779,328 is 70483920.
