Given numbers are 427,386,856,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 427,386,856,765 is 53966019240.
Find LCM of 427,386,856,765 with Prime Factorization
2 | 427, 386, 856, 765 |
427, 193, 428, 765 |
Multiply the prime numbers at the bottom and the left side.
2 x 427 x 193 x 428 x 765 = 53966019240
Therefore, the lowest common multiple of 427,386,856,765 is 53966019240.
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.
427 x 386 x 856 x 765 = 107932038480
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.
427 : 1, 7, 61, 427
386 : 1, 2, 193, 386
856 : 1, 2, 4, 8, 107, 214, 428, 856
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,386,856,765, is 1.
Now, the common factors can be found like this.
427:7x 61
386:2x 193
856:2x 2x 2x 107
765:3x 3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 107932038480/(1x2)
LCM = 107932038480/2
LCM = 53966019240
Thus, we can understand that the LCM of 427,386,856,765 is 53966019240.
