Calculate the LCM of 821,551,688,645

Given numbers are 821,551,688,645

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

The LCM of 821,551,688,645 is 4668468720.

Find LCM of 821,551,688,645 with Prime Factorization

43	821, 551, 688, 645
	821, 551, 16, 15

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

43 x 821 x 551 x 16 x 15 = 4668468720

LCM Formula to Find Lowest Common Multiple of 821,551,688,645

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 551 x 688 x 645 = 200744154960

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

551 : 1, 19, 29, 551

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,551,688,645, is 1.

Now, the common factors can be found like this.

821:821

551:19x 29

688:2x 2x 2x 2x 43

645:3x 5x 43

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

43 = 43

Therefore, the value for common factors is 43.

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 = 200744154960/(1x43)

LCM = 200744154960/43

LCM = 4668468720

Thus, we can understand that the LCM of 821,551,688,645 is 4668468720.
