Calculate the LCM of 242,745,209,392

Given numbers are 242,745,209,392

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

The LCM of 242,745,209,392 is 671399960.

Find LCM of 242,745,209,392 with Prime Factorization


2 242, 745, 209, 392
11 121, 745, 209, 196
11, 745, 19, 196

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

2 x 11 x 11 x 745 x 19 x 196 = 671399960

Therefore, the lowest common multiple of 242,745,209,392 is 671399960.

LCM Formula to Find Lowest Common Multiple of 242,745,209,392

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.

242 x 745 x 209 x 392 = 14770799120

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.

242 : 1, 2, 11, 22, 121, 242

745 : 1, 5, 149, 745

209 : 1, 11, 19, 209

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,745,209,392, is 1.

Now, the common factors can be found like this.

242:2x 11x 11

745:5x 149

209:11x 19

392:2x 2x 2x 7x 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 11 = 22

Therefore, the value for common factors is 22.

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 = 14770799120/(1x22)

LCM = 14770799120/22

LCM = 671399960

Thus, we can understand that the LCM of 242,745,209,392 is 671399960.
