Given numbers are 377,478,777,638,490
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 377,478,777,638,490 is 53907723870.
Find LCM of 377,478,777,638,490 with Prime Factorization
| 2 | 377, 478, 777, 638, 490 |
| 7 | 377, 239, 777, 319, 245 |
| 29 | 377, 239, 111, 319, 35 |
| 13, 239, 111, 11, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 29 x 13 x 239 x 111 x 11 x 35 = 53907723870
Therefore, the lowest common multiple of 377,478,777,638,490 is 53907723870.
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.
377 x 478 x 777 x 638 x 490 = 43773071782440
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.
377 : 1, 13, 29, 377
478 : 1, 2, 239, 478
777 : 1, 3, 7, 21, 37, 111, 259, 777
638 : 1, 2, 11, 22, 29, 58, 319, 638
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 377,478,777,638,490, is 1.
Now, the common factors can be found like this.
377:13x 29
478:2x 239
777:3x 7x 37
638:2x 11x 29
490:2x 5x 7x 7
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 7x 29 = 812
Therefore, the value for common factors is 812.
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 = 43773071782440/(1x812)
LCM = 43773071782440/812
LCM = 53907723870
Thus, we can understand that the LCM of 377,478,777,638,490 is 53907723870.
