Given numbers are 102,478,412,956,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 102,478,412,956,690 is 577514820.
Find LCM of 102,478,412,956,690 with Prime Factorization
| 2 | 102, 478, 412, 956, 690 |
| 2 | 51, 239, 206, 478, 345 |
| 3 | 51, 239, 103, 239, 345 |
| 239 | 17, 239, 103, 239, 115 |
| 17, 1, 103, 1, 115 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 239 x 17 x 1 x 103 x 1 x 115 = 577514820
Therefore, the lowest common multiple of 102,478,412,956,690 is 577514820.
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 478 x 412 x 956 x 690 = 13250500030080
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
478 : 1, 2, 239, 478
412 : 1, 2, 4, 103, 206, 412
956 : 1, 2, 4, 239, 478, 956
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,478,412,956,690, is 2.
Now, the common factors can be found like this.
102:2x 3x 17
478:2x 239
412:2x 2x 103
956:2x 2x 239
690:2x 3x 5x 23
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 2x 2x 3x 239 = 11472
Therefore, the value for common factors is 11472.
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 = 13250500030080/(2x11472)
LCM = 13250500030080/22944
LCM = 577514820
Thus, we can understand that the LCM of 102,478,412,956,690 is 577514820.
