Calculate the LCM of 870,406,706,622

Given numbers are 870,406,706,622

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

The LCM of 870,406,706,622 is 668578470.

Find LCM of 870,406,706,622 with Prime Factorization


2 870, 406, 706, 622
29 435, 203, 353, 311
15, 7, 353, 311

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

2 x 29 x 15 x 7 x 353 x 311 = 668578470

Therefore, the lowest common multiple of 870,406,706,622 is 668578470.

LCM Formula to Find Lowest Common Multiple of 870,406,706,622

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.

870 x 406 x 706 x 622 = 155110205040

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.

870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870

406 : 1, 2, 7, 14, 29, 58, 203, 406

706 : 1, 2, 353, 706

622 : 1, 2, 311, 622

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 870,406,706,622, is 2.

Now, the common factors can be found like this.

870:2x 3x 5x 29

406:2x 7x 29

706:2x 353

622:2x 311

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 29 = 116

Therefore, the value for common factors is 116.

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 = 155110205040/(2x116)

LCM = 155110205040/232

LCM = 668578470

Thus, we can understand that the LCM of 870,406,706,622 is 668578470.
