Calculate the LCM of 711,657,821,511

Given numbers are 711,657,821,511

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

The LCM of 711,657,821,511 is 298286541.

Find LCM of 711,657,821,511 with Prime Factorization


3 711, 657, 821, 511
3 237, 219, 821, 511
73 79, 73, 821, 511
79, 1, 821, 7

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

3 x 3 x 73 x 79 x 1 x 821 x 7 = 298286541

Therefore, the lowest common multiple of 711,657,821,511 is 298286541.

LCM Formula to Find Lowest Common Multiple of 711,657,821,511

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.

711 x 657 x 821 x 511 = 195974257437

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.

711 : 1, 3, 9, 79, 237, 711

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

821 : 1, 821

511 : 1, 7, 73, 511

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 711,657,821,511, is 1.

Now, the common factors can be found like this.

711:3x 3x 79

657:3x 3x 73

821:821

511:7x 73

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

3x 3x 73 = 657

Therefore, the value for common factors is 657.

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 = 195974257437/(1x657)

LCM = 195974257437/657

LCM = 298286541

Thus, we can understand that the LCM of 711,657,821,511 is 298286541.
