Given numbers are 437,851,420

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

The LCM of 437,851,420 is 6790980.

Find LCM of 437,851,420 with Prime Factorization

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

23 x 19 x 37 x 420 = 6790980

Therefore, the lowest common multiple of 437,851,420 is 6790980.

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.

437 x 851 x 420 = 156192540

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.

437 : 1, 19, 23, 437

851 : 1, 23, 37, 851

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,851,420, is 1.

Now, the common factors can be found like this.

437:19x 23

851:23x 37

420:2x 2x 3x 5x 7

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

23 = 23

Therefore, the value for common factors is 23.

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 = 156192540/(1x23)

LCM = 156192540/23

LCM = 6790980

Thus, we can understand that the LCM of 437,851,420 is 6790980.

Here are some samples of LCM of two or more Numbers calculations.
