Given numbers are 276,476,421,407

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

The LCM of 276,476,421,407 is 5627720868.

Find LCM of 276,476,421,407 with Prime Factorization

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

2 x 2 x 69 x 119 x 421 x 407 = 5627720868

Therefore, the lowest common multiple of 276,476,421,407 is 5627720868.

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.

276 x 476 x 421 x 407 = 22510883472

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.

276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276

476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476

421 : 1, 421

407 : 1, 11, 37, 407

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 276,476,421,407, is 1.

Now, the common factors can be found like this.

276:2x 2x 3x 23

476:2x 2x 7x 17

421:421

407:11x 37

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 = 22510883472/(1x4)

LCM = 22510883472/4

LCM = 5627720868

Thus, we can understand that the LCM of 276,476,421,407 is 5627720868.
