Calculate the LCM of 478,554,209,690

Given numbers are 478,554,209,690

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

The LCM of 478,554,209,690 is 9547134630.

Find LCM of 478,554,209,690 with Prime Factorization


2 478, 554, 209, 690
239, 277, 209, 345

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

2 x 239 x 277 x 209 x 345 = 9547134630

Therefore, the lowest common multiple of 478,554,209,690 is 9547134630.

LCM Formula to Find Lowest Common Multiple of 478,554,209,690

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.

478 x 554 x 209 x 690 = 38188538520

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.

478 : 1, 2, 239, 478

554 : 1, 2, 277, 554

209 : 1, 11, 19, 209

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,554,209,690, is 1.

Now, the common factors can be found like this.

478:2x 239

554:2x 277

209:11x 19

690:2x 3x 5x 23

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 38188538520/(1x4)

LCM = 38188538520/4

LCM = 9547134630

Thus, we can understand that the LCM of 478,554,209,690 is 9547134630.
