Given numbers are 387,989,779,902
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 387,989,779,902 is 152545338.
Find LCM of 387,989,779,902 with Prime Factorization
| 41 | 387, 989, 779, 902 |
| 43 | 387, 989, 19, 22 |
| 9, 23, 19, 22 |
Multiply the prime numbers at the bottom and the left side.
41 x 43 x 9 x 23 x 19 x 22 = 152545338
Therefore, the lowest common multiple of 387,989,779,902 is 152545338.
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.
387 x 989 x 779 x 902 = 268937430894
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.
387 : 1, 3, 9, 43, 129, 387
989 : 1, 23, 43, 989
779 : 1, 19, 41, 779
902 : 1, 2, 11, 22, 41, 82, 451, 902
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,989,779,902, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
989:23x 43
779:19x 41
902:2x 11x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
41x 43 = 1763
Therefore, the value for common factors is 1763.
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 = 268937430894/(1x1763)
LCM = 268937430894/1763
LCM = 152545338
Thus, we can understand that the LCM of 387,989,779,902 is 152545338.
