Given numbers are 420,798,834,275

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

The LCM of 420,798,834,275 is 61007100.

Find LCM of 420,798,834,275 with Prime Factorization

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

2 x 3 x 5 x 7 x 2 x 19 x 139 x 55 = 61007100

Therefore, the lowest common multiple of 420,798,834,275 is 61007100.

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 798 x 834 x 275 = 76868946000

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

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

834 : 1, 2, 3, 6, 139, 278, 417, 834

275 : 1, 5, 11, 25, 55, 275

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,798,834,275, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

798:2x 3x 7x 19

834:2x 3x 139

275:5x 5x 11

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

2x 2x 3x 3x 5x 7 = 1260

Therefore, the value for common factors is 1260.

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 = 76868946000/(1x1260)

LCM = 76868946000/1260

LCM = 61007100

Thus, we can understand that the LCM of 420,798,834,275 is 61007100.
