Given numbers are 227,212,420,764

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

The LCM of 227,212,420,764 is 965126820.

Find LCM of 227,212,420,764 with Prime Factorization

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

2 x 2 x 227 x 53 x 105 x 191 = 965126820

Therefore, the lowest common multiple of 227,212,420,764 is 965126820.

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.

227 x 212 x 420 x 764 = 15442029120

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.

227 : 1, 227

212 : 1, 2, 4, 53, 106, 212

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

764 : 1, 2, 4, 191, 382, 764

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 227,212,420,764, is 1.

Now, the common factors can be found like this.

227:227

212:2x 2x 53

420:2x 2x 3x 5x 7

764:2x 2x 191

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 15442029120/(1x16)

LCM = 15442029120/16

LCM = 965126820

Thus, we can understand that the LCM of 227,212,420,764 is 965126820.

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

• LCM of 650, 308, 624, 156
