LCM Formula to Find Lowest Common Multiple of 639,968,490,137

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.

639 x 968 x 490 x 137 = 41523395760

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.

639 : 1, 3, 9, 71, 213, 639

968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

137 : 1, 137

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,968,490,137, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

968:2x 2x 2x 11x 11

490:2x 5x 7x 7

137:137

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 41523395760/(1x2)

LCM = 41523395760/2

LCM = 20761697880

Thus, we can understand that the LCM of 639,968,490,137 is 20761697880.
