Given numbers are 640,748,877,201

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

The LCM of 640,748,877,201 is 21096831360.

Find LCM of 640,748,877,201 with Prime Factorization

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

2 x 2 x 160 x 187 x 877 x 201 = 21096831360

Therefore, the lowest common multiple of 640,748,877,201 is 21096831360.

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 748 x 877 x 201 = 84387325440

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

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

877 : 1, 877

201 : 1, 3, 67, 201

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,748,877,201, is 1.

Now, the common factors can be found like this.

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

748:2x 2x 11x 17

877:877

201:3x 67

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 84387325440/(1x4)

LCM = 84387325440/4

LCM = 21096831360

Thus, we can understand that the LCM of 640,748,877,201 is 21096831360.
