Given numbers are 512,817,671,989,428
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 512,817,671,989,428 is 690758362624.
Find LCM of 512,817,671,989,428 with Prime Factorization
2 | 512, 817, 671, 989, 428 |
2 | 256, 817, 671, 989, 214 |
43 | 128, 817, 671, 989, 107 |
128, 19, 671, 23, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 128 x 19 x 671 x 23 x 107 = 690758362624
Therefore, the lowest common multiple of 512,817,671,989,428 is 690758362624.
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.
512 x 817 x 671 x 989 x 428 = 118810438371328
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.
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
817 : 1, 19, 43, 817
671 : 1, 11, 61, 671
989 : 1, 23, 43, 989
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 512,817,671,989,428, is 1.
Now, the common factors can be found like this.
512:2x 2x 2x 2x 2x 2x 2x 2x 2
817:19x 43
671:11x 61
989:23x 43
428:2x 2x 107
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 43 = 172
Therefore, the value for common factors is 172.
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 = 118810438371328/(1x172)
LCM = 118810438371328/172
LCM = 690758362624
Thus, we can understand that the LCM of 512,817,671,989,428 is 690758362624.
