Given numbers are 638,748,462,973,532

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

The LCM of 638,748,462,973,532 is 1203060012.

Find LCM of 638,748,462,973,532 with Prime Factorization

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

2 x 2 x 7 x 11 x 29 x 17 x 3 x 139 x 19 = 1203060012

Therefore, the lowest common multiple of 638,748,462,973,532 is 1203060012.

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.

638 x 748 x 462 x 973 x 532 = 114127084978368

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

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

462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462

973 : 1, 7, 139, 973

532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,748,462,973,532, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

748:2x 2x 11x 17

462:2x 3x 7x 11

973:7x 139

532:2x 2x 7x 19

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 2x 7x 7x 11x 11 = 94864

Therefore, the value for common factors is 94864.

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 = 114127084978368/(1x94864)

LCM = 114127084978368/94864

LCM = 1203060012

Thus, we can understand that the LCM of 638,748,462,973,532 is 1203060012.
