Find LCM of 872,381,210,672 with Prime Factorization


2 872, 381, 210, 672
2 436, 381, 105, 336
2 218, 381, 105, 168
3 109, 381, 105, 84
7 109, 127, 35, 28
109, 127, 5, 4

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

2 x 2 x 2 x 3 x 7 x 109 x 127 x 5 x 4 = 46512480

Therefore, the lowest common multiple of 872,381,210,672 is 46512480.

LCM Formula to Find Lowest Common Multiple of 872,381,210,672

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.

872 x 381 x 210 x 672 = 46884579840

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.

872 : 1, 2, 4, 8, 109, 218, 436, 872

381 : 1, 3, 127, 381

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,381,210,672, is 1.

Now, the common factors can be found like this.

872:2x 2x 2x 109

381:3x 127

210:2x 3x 5x 7

672:2x 2x 2x 2x 2x 3x 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 2x 2x 3x 3x 7 = 1008

Therefore, the value for common factors is 1008.

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 = 46884579840/(1x1008)

LCM = 46884579840/1008

LCM = 46512480

Thus, we can understand that the LCM of 872,381,210,672 is 46512480.
