Given numbers are 919,654,638,784
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 919,654,638,784 is 75157099248.
Find LCM of 919,654,638,784 with Prime Factorization
2 | 919, 654, 638, 784 |
919, 327, 319, 392 |
Multiply the prime numbers at the bottom and the left side.
2 x 919 x 327 x 319 x 392 = 75157099248
Therefore, the lowest common multiple of 919,654,638,784 is 75157099248.
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.
919 x 654 x 638 x 784 = 300628396992
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.
919 : 1, 919
654 : 1, 2, 3, 6, 109, 218, 327, 654
638 : 1, 2, 11, 22, 29, 58, 319, 638
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 919,654,638,784, is 1.
Now, the common factors can be found like this.
919:919
654:2x 3x 109
638:2x 11x 29
784:2x 2x 2x 2x 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 2 = 4
Therefore, the value for common factors is 4.
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 = 300628396992/(1x4)
LCM = 300628396992/4
LCM = 75157099248
Thus, we can understand that the LCM of 919,654,638,784 is 75157099248.
