Given numbers are 478,769,762,391,762
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,769,762,391,762 is 54759058122.
Find LCM of 478,769,762,391,762 with Prime Factorization
| 2 | 478, 769, 762, 391, 762 |
| 3 | 239, 769, 381, 391, 381 |
| 127 | 239, 769, 127, 391, 127 |
| 239, 769, 1, 391, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 127 x 239 x 769 x 1 x 391 x 1 = 54759058122
Therefore, the lowest common multiple of 478,769,762,391,762 is 54759058122.
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.
478 x 769 x 762 x 391 x 762 = 83452804577928
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.
478 : 1, 2, 239, 478
769 : 1, 769
762 : 1, 2, 3, 6, 127, 254, 381, 762
391 : 1, 17, 23, 391
762 : 1, 2, 3, 6, 127, 254, 381, 762
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,769,762,391,762, is 1.
Now, the common factors can be found like this.
478:2x 239
769:769
762:2x 3x 127
391:17x 23
762:2x 3x 127
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 3x 127 = 1524
Therefore, the value for common factors is 1524.
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 = 83452804577928/(1x1524)
LCM = 83452804577928/1524
LCM = 54759058122
Thus, we can understand that the LCM of 478,769,762,391,762 is 54759058122.
