Given numbers are 619,745,138,686

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

The LCM of 619,745,138,686 is 21828310770.

Find LCM of 619,745,138,686 with Prime Factorization

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

2 x 619 x 745 x 69 x 343 = 21828310770

Therefore, the lowest common multiple of 619,745,138,686 is 21828310770.

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.

619 x 745 x 138 x 686 = 43656621540

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.

619 : 1, 619

745 : 1, 5, 149, 745

138 : 1, 2, 3, 6, 23, 46, 69, 138

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,745,138,686, is 1.

Now, the common factors can be found like this.

619:619

745:5x 149

138:2x 3x 23

686:2x 7x 7x 7

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 = 43656621540/(1x2)

LCM = 43656621540/2

LCM = 21828310770

Thus, we can understand that the LCM of 619,745,138,686 is 21828310770.
