Given numbers are 620,974,451,473,781

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

The LCM of 620,974,451,473,781 is 415742091820.

Find LCM of 620,974,451,473,781 with Prime Factorization

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

2 x 11 x 310 x 487 x 41 x 43 x 71 = 415742091820

Therefore, the lowest common multiple of 620,974,451,473,781 is 415742091820.

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.

620 x 974 x 451 x 473 x 781 = 100609586220440

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

974 : 1, 2, 487, 974

451 : 1, 11, 41, 451

473 : 1, 11, 43, 473

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,974,451,473,781, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

974:2x 487

451:11x 41

473:11x 43

781:11x 71

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

2x 11x 11 = 242

Therefore, the value for common factors is 242.

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 = 100609586220440/(1x242)

LCM = 100609586220440/242

LCM = 415742091820

Thus, we can understand that the LCM of 620,974,451,473,781 is 415742091820.
