Given numbers are 254,187,715,462
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 254,187,715,462 is 64834770.
Find LCM of 254,187,715,462 with Prime Factorization
| 2 | 254, 187, 715, 462 |
| 11 | 127, 187, 715, 231 |
| 127, 17, 65, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 127 x 17 x 65 x 21 = 64834770
Therefore, the lowest common multiple of 254,187,715,462 is 64834770.
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.
254 x 187 x 715 x 462 = 15690014340
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.
254 : 1, 2, 127, 254
187 : 1, 11, 17, 187
715 : 1, 5, 11, 13, 55, 65, 143, 715
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,187,715,462, is 1.
Now, the common factors can be found like this.
254:2x 127
187:11x 17
715:5x 11x 13
462:2x 3x 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 11x 11 = 242
Therefore, the value for common factors is 242.
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 = 15690014340/(1x242)
LCM = 15690014340/242
LCM = 64834770
Thus, we can understand that the LCM of 254,187,715,462 is 64834770.
