LCM Formula to Find Lowest Common Multiple of 700,786,840,580,991

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.

700 x 786 x 840 x 580 x 991 = 265644923040000

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.

700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700

786 : 1, 2, 3, 6, 131, 262, 393, 786

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

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 700,786,840,580,991, is 1.

Now, the common factors can be found like this.

700:2x 2x 5x 5x 7

786:2x 3x 131

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

580:2x 2x 5x 29

991:991

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 5x 7 = 16800

Therefore, the value for common factors is 16800.

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 = 265644923040000/(1x16800)

LCM = 265644923040000/16800

LCM = 15812197800

Thus, we can understand that the LCM of 700,786,840,580,991 is 15812197800.
