Given numbers are 102,116,493,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 102,116,493,638 is 65076.
Find LCM of 102,116,493,638 with Prime Factorization
2 | 102, 116, 493, 638 |
17 | 51, 58, 493, 319 |
29 | 3, 58, 29, 319 |
3, 2, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 29 x 3 x 2 x 1 x 11 = 65076
Therefore, the lowest common multiple of 102,116,493,638 is 65076.
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.
102 x 116 x 493 x 638 = 3721566288
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.
102 : 1, 2, 3, 6, 17, 34, 51, 102
116 : 1, 2, 4, 29, 58, 116
493 : 1, 17, 29, 493
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,116,493,638, is 1.
Now, the common factors can be found like this.
102:2x 3x 17
116:2x 2x 29
493:17x 29
638:2x 11x 29
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 17x 29x 29 = 57188
Therefore, the value for common factors is 57188.
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 = 3721566288/(1x57188)
LCM = 3721566288/57188
LCM = 65076
Thus, we can understand that the LCM of 102,116,493,638 is 65076.
