Given numbers are 644,868,836,769,222

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

The LCM of 644,868,836,769,222 is 356158378884.

Find LCM of 644,868,836,769,222 with Prime Factorization

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

2 x 2 x 7 x 23 x 31 x 209 x 769 x 111 = 356158378884

Therefore, the lowest common multiple of 644,868,836,769,222 is 356158378884.

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.

644 x 868 x 836 x 769 x 222 = 79779476870016

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

769 : 1, 769

222 : 1, 2, 3, 6, 37, 74, 111, 222

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,868,836,769,222, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

868:2x 2x 7x 31

836:2x 2x 11x 19

769:769

222:2x 3x 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 2x 2x 2x 2x 7 = 224

Therefore, the value for common factors is 224.

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 = 79779476870016/(1x224)

LCM = 79779476870016/224

LCM = 356158378884

Thus, we can understand that the LCM of 644,868,836,769,222 is 356158378884.
