Calculate the LCM of 421,506,383,492

Given numbers are 421,506,383,492

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

The LCM of 421,506,383,492 is 20070883668.

Find LCM of 421,506,383,492 with Prime Factorization


2 421, 506, 383, 492
421, 253, 383, 246

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

2 x 421 x 253 x 383 x 246 = 20070883668

Therefore, the lowest common multiple of 421,506,383,492 is 20070883668.

LCM Formula to Find Lowest Common Multiple of 421,506,383,492

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 506 x 383 x 492 = 40141767336

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

506 : 1, 2, 11, 22, 23, 46, 253, 506

383 : 1, 383

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,506,383,492, is 1.

Now, the common factors can be found like this.

421:421

506:2x 11x 23

383:383

492:2x 2x 3x 41

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 = 40141767336/(1x2)

LCM = 40141767336/2

LCM = 20070883668

Thus, we can understand that the LCM of 421,506,383,492 is 20070883668.
