Calculate the LCM of 868,657,775,491

Given numbers are 868,657,775,491

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

The LCM of 868,657,775,491 is 7000137900.

Find LCM of 868,657,775,491 with Prime Factorization


31 868, 657, 775, 491
28, 657, 25, 491

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

31 x 28 x 657 x 25 x 491 = 7000137900

Therefore, the lowest common multiple of 868,657,775,491 is 7000137900.

LCM Formula to Find Lowest Common Multiple of 868,657,775,491

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.

868 x 657 x 775 x 491 = 217004274900

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.

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

657 : 1, 3, 9, 73, 219, 657

775 : 1, 5, 25, 31, 155, 775

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,657,775,491, is 1.

Now, the common factors can be found like this.

868:2x 2x 7x 31

657:3x 3x 73

775:5x 5x 31

491:491

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

31 = 31

Therefore, the value for common factors is 31.

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 = 217004274900/(1x31)

LCM = 217004274900/31

LCM = 7000137900

Thus, we can understand that the LCM of 868,657,775,491 is 7000137900.
