Given numbers are 386,574,889,748,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 386,574,889,748,688 is 905050830992.
Find LCM of 386,574,889,748,688 with Prime Factorization
| 2 | 386, 574, 889, 748, 688 |
| 2 | 193, 287, 889, 374, 344 |
| 7 | 193, 287, 889, 187, 172 |
| 193, 41, 127, 187, 172 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 193 x 41 x 127 x 187 x 172 = 905050830992
Therefore, the lowest common multiple of 386,574,889,748,688 is 905050830992.
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.
386 x 574 x 889 x 748 x 688 = 101365693071104
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.
386 : 1, 2, 193, 386
574 : 1, 2, 7, 14, 41, 82, 287, 574
889 : 1, 7, 127, 889
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,574,889,748,688, is 1.
Now, the common factors can be found like this.
386:2x 193
574:2x 7x 41
889:7x 127
748:2x 2x 11x 17
688:2x 2x 2x 2x 43
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 7 = 112
Therefore, the value for common factors is 112.
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 = 101365693071104/(1x112)
LCM = 101365693071104/112
LCM = 905050830992
Thus, we can understand that the LCM of 386,574,889,748,688 is 905050830992.
