Given numbers are 974,621,545,218

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

The LCM of 974,621,545,218 is 329645430.

Find LCM of 974,621,545,218 with Prime Factorization

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

2 x 109 x 487 x 621 x 5 x 1 = 329645430

Therefore, the lowest common multiple of 974,621,545,218 is 329645430.

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.

974 x 621 x 545 x 218 = 71862703740

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.

974 : 1, 2, 487, 974

621 : 1, 3, 9, 23, 27, 69, 207, 621

545 : 1, 5, 109, 545

218 : 1, 2, 109, 218

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,621,545,218, is 1.

Now, the common factors can be found like this.

974:2x 487

621:3x 3x 3x 23

545:5x 109

218:2x 109

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 109 = 218

Therefore, the value for common factors is 218.

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 = 71862703740/(1x218)

LCM = 71862703740/218

LCM = 329645430

Thus, we can understand that the LCM of 974,621,545,218 is 329645430.
