Find LCM of 836,436,208,123,798 with Prime Factorization


2 836, 436, 208, 123, 798
2 418, 218, 104, 123, 399
3 209, 109, 52, 123, 399
19 209, 109, 52, 41, 133
11, 109, 52, 41, 7

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 3 x 19 x 11 x 109 x 52 x 41 x 7 = 4079803728

Therefore, the lowest common multiple of 836,436,208,123,798 is 4079803728.

LCM Formula to Find Lowest Common Multiple of 836,436,208,123,798

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.

836 x 436 x 208 x 123 x 798 = 7441561999872

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.

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

436 : 1, 2, 4, 109, 218, 436

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

123 : 1, 3, 41, 123

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,436,208,123,798, is 1.

Now, the common factors can be found like this.

836:2x 2x 11x 19

436:2x 2x 109

208:2x 2x 2x 2x 13

123:3x 41

798:2x 3x 7x 19

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 2x 2x 2x 3x 19 = 1824

Therefore, the value for common factors is 1824.

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 = 7441561999872/(1x1824)

LCM = 7441561999872/1824

LCM = 4079803728

Thus, we can understand that the LCM of 836,436,208,123,798 is 4079803728.
