Given numbers are 420,832,337,253

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

The LCM of 420,832,337,253 is 7448400960.

Find LCM of 420,832,337,253 with Prime Factorization

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

2 x 2 x 105 x 208 x 337 x 253 = 7448400960

Therefore, the lowest common multiple of 420,832,337,253 is 7448400960.

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.

420 x 832 x 337 x 253 = 29793603840

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.

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

832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832

337 : 1, 337

253 : 1, 11, 23, 253

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,832,337,253, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

832:2x 2x 2x 2x 2x 2x 13

337:337

253:11x 23

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 29793603840/(1x4)

LCM = 29793603840/4

LCM = 7448400960

Thus, we can understand that the LCM of 420,832,337,253 is 7448400960.
