Given numbers are 640,953,889,790,630

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

The LCM of 640,953,889,790,630 is 385517623680.

Find LCM of 640,953,889,790,630 with Prime Factorization

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

2 x 5 x 7 x 64 x 953 x 127 x 79 x 9 = 385517623680

Therefore, the lowest common multiple of 640,953,889,790,630 is 385517623680.

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.

640 x 953 x 889 x 790 x 630 = 269862336576000

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.

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

953 : 1, 953

889 : 1, 7, 127, 889

790 : 1, 2, 5, 10, 79, 158, 395, 790

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,953,889,790,630, is 1.

Now, the common factors can be found like this.

640:2x 2x 2x 2x 2x 2x 2x 5

953:953

889:7x 127

790:2x 5x 79

630:2x 3x 3x 5x 7

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 5x 5x 7 = 700

Therefore, the value for common factors is 700.

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 = 269862336576000/(1x700)

LCM = 269862336576000/700

LCM = 385517623680

Thus, we can understand that the LCM of 640,953,889,790,630 is 385517623680.
