Given numbers are 781,620,473,398

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

The LCM of 781,620,473,398 is 4143470540.

Find LCM of 781,620,473,398 with Prime Factorization

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

2 x 11 x 71 x 310 x 43 x 199 = 4143470540

Therefore, the lowest common multiple of 781,620,473,398 is 4143470540.

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.

781 x 620 x 473 x 398 = 91156351880

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.

781 : 1, 11, 71, 781

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

473 : 1, 11, 43, 473

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,620,473,398, is 1.

Now, the common factors can be found like this.

781:11x 71

620:2x 2x 5x 31

473:11x 43

398:2x 199

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 91156351880/(1x22)

LCM = 91156351880/22

LCM = 4143470540

Thus, we can understand that the LCM of 781,620,473,398 is 4143470540.
