Calculate the LCM of 641,762,208,364

Given numbers are 641,762,208,364

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

The LCM of 641,762,208,364 is 355585776.

Find LCM of 641,762,208,364 with Prime Factorization


2 641, 762, 208, 364
2 641, 381, 104, 182
13 641, 381, 52, 91
641, 381, 4, 7

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

2 x 2 x 13 x 641 x 381 x 4 x 7 = 355585776

Therefore, the lowest common multiple of 641,762,208,364 is 355585776.

LCM Formula to Find Lowest Common Multiple of 641,762,208,364

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.

641 x 762 x 208 x 364 = 36980920704

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.

641 : 1, 641

762 : 1, 2, 3, 6, 127, 254, 381, 762

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,762,208,364, is 1.

Now, the common factors can be found like this.

641:641

762:2x 3x 127

208:2x 2x 2x 2x 13

364:2x 2x 7x 13

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

2x 2x 2x 13 = 104

Therefore, the value for common factors is 104.

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 = 36980920704/(1x104)

LCM = 36980920704/104

LCM = 355585776

Thus, we can understand that the LCM of 641,762,208,364 is 355585776.
