Given numbers are 667,570,644,747

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

The LCM of 667,570,644,747 is 1325342340.

Find LCM of 667,570,644,747 with Prime Factorization

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

2 x 3 x 23 x 29 x 95 x 14 x 249 = 1325342340

Therefore, the lowest common multiple of 667,570,644,747 is 1325342340.

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.

667 x 570 x 644 x 747 = 182897242920

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.

667 : 1, 23, 29, 667

570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570

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

747 : 1, 3, 9, 83, 249, 747

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,570,644,747, is 1.

Now, the common factors can be found like this.

667:23x 29

570:2x 3x 5x 19

644:2x 2x 7x 23

747:3x 3x 83

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

2x 3x 23 = 138

Therefore, the value for common factors is 138.

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 = 182897242920/(1x138)

LCM = 182897242920/138

LCM = 1325342340

Thus, we can understand that the LCM of 667,570,644,747 is 1325342340.
