LCM Formula to Find Lowest Common Multiple of 832,620,840,651

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.

832 x 620 x 840 x 651 = 282081945600

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.

832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

651 : 1, 3, 7, 21, 31, 93, 217, 651

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 832,620,840,651, is 1.

Now, the common factors can be found like this.

832:2x 2x 2x 2x 2x 2x 13

620:2x 2x 5x 31

840:2x 2x 2x 3x 5x 7

651:3x 7x 31

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 5x 7x 31 = 104160

Therefore, the value for common factors is 104160.

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 = 282081945600/(1x104160)

LCM = 282081945600/104160

LCM = 2708160

Thus, we can understand that the LCM of 832,620,840,651 is 2708160.
