Find LCM of 820,456,716,172,931 with Prime Factorization


2 820, 456, 716, 172, 931
2 410, 228, 358, 86, 931
19 205, 114, 179, 43, 931
205, 6, 179, 43, 49

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

2 x 2 x 19 x 205 x 6 x 179 x 43 x 49 = 35256262440

Therefore, the lowest common multiple of 820,456,716,172,931 is 35256262440.

LCM Formula to Find Lowest Common Multiple of 820,456,716,172,931

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.

820 x 456 x 716 x 172 x 931 = 42871615127040

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.

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

716 : 1, 2, 4, 179, 358, 716

172 : 1, 2, 4, 43, 86, 172

931 : 1, 7, 19, 49, 133, 931

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,456,716,172,931, is 1.

Now, the common factors can be found like this.

820:2x 2x 5x 41

456:2x 2x 2x 3x 19

716:2x 2x 179

172:2x 2x 43

931:7x 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 2x 19 = 1216

Therefore, the value for common factors is 1216.

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 = 42871615127040/(1x1216)

LCM = 42871615127040/1216

LCM = 35256262440

Thus, we can understand that the LCM of 820,456,716,172,931 is 35256262440.
