Given numbers are 619,681,790,686

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

The LCM of 619,681,790,686 is 114224422830.

Find LCM of 619,681,790,686 with Prime Factorization

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

2 x 619 x 681 x 395 x 343 = 114224422830

Therefore, the lowest common multiple of 619,681,790,686 is 114224422830.

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 681 x 790 x 686 = 228448845660

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

681 : 1, 3, 227, 681

790 : 1, 2, 5, 10, 79, 158, 395, 790

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 619,681,790,686, is 1.

Now, the common factors can be found like this.

619:619

681:3x 227

790:2x 5x 79

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 = 228448845660/(1x2)

LCM = 228448845660/2

LCM = 114224422830

Thus, we can understand that the LCM of 619,681,790,686 is 114224422830.
