Given numbers are 743,669,508,220

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

The LCM of 743,669,508,220 is 13888051980.

Find LCM of 743,669,508,220 with Prime Factorization

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

2 x 2 x 743 x 669 x 127 x 55 = 13888051980

Therefore, the lowest common multiple of 743,669,508,220 is 13888051980.

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.

743 x 669 x 508 x 220 = 55552207920

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.

743 : 1, 743

669 : 1, 3, 223, 669

508 : 1, 2, 4, 127, 254, 508

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,669,508,220, is 1.

Now, the common factors can be found like this.

743:743

669:3x 223

508:2x 2x 127

220:2x 2x 5x 11

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 = 55552207920/(1x4)

LCM = 55552207920/4

LCM = 13888051980

Thus, we can understand that the LCM of 743,669,508,220 is 13888051980.
