Given numbers are 640,169,894,737,607

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

The LCM of 640,169,894,737,607 is 21628698199680.

Find LCM of 640,169,894,737,607 with Prime Factorization

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

2 x 320 x 169 x 447 x 737 x 607 = 21628698199680

Therefore, the lowest common multiple of 640,169,894,737,607 is 21628698199680.

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 169 x 894 x 737 x 607 = 43257396399360

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

169 : 1, 13, 169

894 : 1, 2, 3, 6, 149, 298, 447, 894

737 : 1, 11, 67, 737

607 : 1, 607

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,169,894,737,607, is 1.

Now, the common factors can be found like this.

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

169:13x 13

894:2x 3x 149

737:11x 67

607:607

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 = 43257396399360/(1x2)

LCM = 43257396399360/2

LCM = 21628698199680

Thus, we can understand that the LCM of 640,169,894,737,607 is 21628698199680.
