Given numbers are 639,160,786,652

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 639,160,786,652 is 2183130720.

Find LCM of 639,160,786,652 with Prime Factorization

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

2 x 2 x 3 x 213 x 40 x 131 x 163 = 2183130720

Therefore, the lowest common multiple of 639,160,786,652 is 2183130720.

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 160 x 786 x 652 = 52395137280

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

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

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

652 : 1, 2, 4, 163, 326, 652

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,160,786,652, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

160:2x 2x 2x 2x 2x 5

786:2x 3x 131

652:2x 2x 163

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 3 = 24

Therefore, the value for common factors is 24.

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 = 52395137280/(1x24)

LCM = 52395137280/24

LCM = 2183130720

Thus, we can understand that the LCM of 639,160,786,652 is 2183130720.
