Given numbers are 658,129,938,630,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 658,129,938,630,391 is 33354806310.
Find LCM of 658,129,938,630,391 with Prime Factorization
| 2 | 658, 129, 938, 630, 391 |
| 3 | 329, 129, 469, 315, 391 |
| 7 | 329, 43, 469, 105, 391 |
| 47, 43, 67, 15, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 47 x 43 x 67 x 15 x 391 = 33354806310
Therefore, the lowest common multiple of 658,129,938,630,391 is 33354806310.
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.
658 x 129 x 938 x 630 x 391 = 19612626110280
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.
658 : 1, 2, 7, 14, 47, 94, 329, 658
129 : 1, 3, 43, 129
938 : 1, 2, 7, 14, 67, 134, 469, 938
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,129,938,630,391, is 1.
Now, the common factors can be found like this.
658:2x 7x 47
129:3x 43
938:2x 7x 67
630:2x 3x 3x 5x 7
391:17x 23
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 7x 7 = 588
Therefore, the value for common factors is 588.
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 = 19612626110280/(1x588)
LCM = 19612626110280/588
LCM = 33354806310
Thus, we can understand that the LCM of 658,129,938,630,391 is 33354806310.
