Calculate the LCM of 697,639,909,303

Given numbers are 697,639,909,303

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

The LCM of 697,639,909,303 is 44983683.

Find LCM of 697,639,909,303 with Prime Factorization


3 697, 639, 909, 303
3 697, 213, 303, 101
101 697, 71, 101, 101
697, 71, 1, 1

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

3 x 3 x 101 x 697 x 71 x 1 x 1 = 44983683

Therefore, the lowest common multiple of 697,639,909,303 is 44983683.

LCM Formula to Find Lowest Common Multiple of 697,639,909,303

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.

697 x 639 x 909 x 303 = 122670503541

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.

697 : 1, 17, 41, 697

639 : 1, 3, 9, 71, 213, 639

909 : 1, 3, 9, 101, 303, 909

303 : 1, 3, 101, 303

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,639,909,303, is 1.

Now, the common factors can be found like this.

697:17x 41

639:3x 3x 71

909:3x 3x 101

303:3x 101

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 3x 101 = 2727

Therefore, the value for common factors is 2727.

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 = 122670503541/(1x2727)

LCM = 122670503541/2727

LCM = 44983683

Thus, we can understand that the LCM of 697,639,909,303 is 44983683.
