Calculate the LCM of 420,647,529,757,706

Given numbers are 420,647,529,757,706

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

The LCM of 420,647,529,757,706 is 38413141671660.

Find LCM of 420,647,529,757,706 with Prime Factorization


2 420, 647, 529, 757, 706
210, 647, 529, 757, 353

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

2 x 210 x 647 x 529 x 757 x 353 = 38413141671660

Therefore, the lowest common multiple of 420,647,529,757,706 is 38413141671660.

LCM Formula to Find Lowest Common Multiple of 420,647,529,757,706

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.

420 x 647 x 529 x 757 x 706 = 76826283343320

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.

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

647 : 1, 647

529 : 1, 23, 529

757 : 1, 757

706 : 1, 2, 353, 706

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,647,529,757,706, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

647:647

529:23x 23

757:757

706:2x 353

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

2 = 2

Therefore, the value for common factors is 2.

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 = 76826283343320/(1x2)

LCM = 76826283343320/2

LCM = 38413141671660

Thus, we can understand that the LCM of 420,647,529,757,706 is 38413141671660.
