Given numbers are 381,478,723,609,654
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,478,723,609,654 is 971163721626.
Find LCM of 381,478,723,609,654 with Prime Factorization
| 2 | 381, 478, 723, 609, 654 |
| 3 | 381, 239, 723, 609, 327 |
| 127, 239, 241, 203, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 127 x 239 x 241 x 203 x 109 = 971163721626
Therefore, the lowest common multiple of 381,478,723,609,654 is 971163721626.
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.
381 x 478 x 723 x 609 x 654 = 52442840967804
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.
381 : 1, 3, 127, 381
478 : 1, 2, 239, 478
723 : 1, 3, 241, 723
609 : 1, 3, 7, 21, 29, 87, 203, 609
654 : 1, 2, 3, 6, 109, 218, 327, 654
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,478,723,609,654, is 1.
Now, the common factors can be found like this.
381:3x 127
478:2x 239
723:3x 241
609:3x 7x 29
654:2x 3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 52442840967804/(1x54)
LCM = 52442840967804/54
LCM = 971163721626
Thus, we can understand that the LCM of 381,478,723,609,654 is 971163721626.
