Given numbers are 619,430,688,734

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

The LCM of 619,430,688,734 is 781475120.

Find LCM of 619,430,688,734 with Prime Factorization

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

2 x 43 x 619 x 5 x 8 x 367 = 781475120

Therefore, the lowest common multiple of 619,430,688,734 is 781475120.

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 430 x 688 x 734 = 134413720640

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

430 : 1, 2, 5, 10, 43, 86, 215, 430

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

734 : 1, 2, 367, 734

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,430,688,734, is 1.

Now, the common factors can be found like this.

619:619

430:2x 5x 43

688:2x 2x 2x 2x 43

734:2x 367

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 43 = 172

Therefore, the value for common factors is 172.

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 = 134413720640/(1x172)

LCM = 134413720640/172

LCM = 781475120

Thus, we can understand that the LCM of 619,430,688,734 is 781475120.
