Given numbers are 152,107,638,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 152,107,638,418 is 5188216.
Find LCM of 152,107,638,418 with Prime Factorization
2 | 152, 107, 638, 418 |
11 | 76, 107, 319, 209 |
19 | 76, 107, 29, 19 |
4, 107, 29, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 19 x 4 x 107 x 29 x 1 = 5188216
Therefore, the lowest common multiple of 152,107,638,418 is 5188216.
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.
152 x 107 x 638 x 418 = 4337348576
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.
152 : 1, 2, 4, 8, 19, 38, 76, 152
107 : 1, 107
638 : 1, 2, 11, 22, 29, 58, 319, 638
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 152,107,638,418, is 1.
Now, the common factors can be found like this.
152:2x 2x 2x 19
107:107
638:2x 11x 29
418:2x 11x 19
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 11x 19 = 836
Therefore, the value for common factors is 836.
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 = 4337348576/(1x836)
LCM = 4337348576/836
LCM = 5188216
Thus, we can understand that the LCM of 152,107,638,418 is 5188216.
