Given numbers are 421,869,628,964

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

The LCM of 421,869,628,964 is 55370514452.

Find LCM of 421,869,628,964 with Prime Factorization

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

2 x 2 x 421 x 869 x 157 x 241 = 55370514452

Therefore, the lowest common multiple of 421,869,628,964 is 55370514452.

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.

421 x 869 x 628 x 964 = 221482057808

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.

421 : 1, 421

869 : 1, 11, 79, 869

628 : 1, 2, 4, 157, 314, 628

964 : 1, 2, 4, 241, 482, 964

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,869,628,964, is 1.

Now, the common factors can be found like this.

421:421

869:11x 79

628:2x 2x 157

964:2x 2x 241

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 = 221482057808/(1x4)

LCM = 221482057808/4

LCM = 55370514452

Thus, we can understand that the LCM of 421,869,628,964 is 55370514452.
