Calculate the LCM of 821,160,142,638

Given numbers are 821,160,142,638

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

The LCM of 821,160,142,638 is 2975172640.

Find LCM of 821,160,142,638 with Prime Factorization

2	821, 160, 142, 638
	821, 80, 71, 319

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

2 x 821 x 80 x 71 x 319 = 2975172640

LCM Formula to Find Lowest Common Multiple of 821,160,142,638

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.

821 x 160 x 142 x 638 = 11900690560

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.

821 : 1, 821

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

142 : 1, 2, 71, 142

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,160,142,638, is 1.

Now, the common factors can be found like this.

821:821

160:2x 2x 2x 2x 2x 5

142:2x 71

638:2x 11x 29

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 11900690560/(1x4)

LCM = 11900690560/4

LCM = 2975172640

Thus, we can understand that the LCM of 821,160,142,638 is 2975172640.
