Calculate the LCM of 322,790,938,840

Given numbers are 322,790,938,840

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

The LCM of 322,790,938,840 is 102260760.

Find LCM of 322,790,938,840 with Prime Factorization


2 322, 790, 938, 840
5 161, 395, 469, 420
7 161, 79, 469, 84
23, 79, 67, 12

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

2 x 5 x 7 x 23 x 79 x 67 x 12 = 102260760

Therefore, the lowest common multiple of 322,790,938,840 is 102260760.

LCM Formula to Find Lowest Common Multiple of 322,790,938,840

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.

322 x 790 x 938 x 840 = 200431089600

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.

322 : 1, 2, 7, 14, 23, 46, 161, 322

790 : 1, 2, 5, 10, 79, 158, 395, 790

938 : 1, 2, 7, 14, 67, 134, 469, 938

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 322,790,938,840, is 2.

Now, the common factors can be found like this.

322:2x 7x 23

790:2x 5x 79

938:2x 7x 67

840:2x 2x 2x 3x 5x 7

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 5x 7x 7 = 980

Therefore, the value for common factors is 980.

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 = 200431089600/(2x980)

LCM = 200431089600/1960

LCM = 102260760

Thus, we can understand that the LCM of 322,790,938,840 is 102260760.
