Given numbers are 935,778,638,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 935,778,638,154 is 147668290.
Find LCM of 935,778,638,154 with Prime Factorization
| 2 | 935, 778, 638, 154 |
| 11 | 935, 389, 319, 77 |
| 85, 389, 29, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 85 x 389 x 29 x 7 = 147668290
Therefore, the lowest common multiple of 935,778,638,154 is 147668290.
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.
935 x 778 x 638 x 154 = 71471452360
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.
935 : 1, 5, 11, 17, 55, 85, 187, 935
778 : 1, 2, 389, 778
638 : 1, 2, 11, 22, 29, 58, 319, 638
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 935,778,638,154, is 1.
Now, the common factors can be found like this.
935:5x 11x 17
778:2x 389
638:2x 11x 29
154:2x 7x 11
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 11 = 484
Therefore, the value for common factors is 484.
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 = 71471452360/(1x484)
LCM = 71471452360/484
LCM = 147668290
Thus, we can understand that the LCM of 935,778,638,154 is 147668290.
