Calculate the LCM of 635,842,640,670

Given numbers are 635,842,640,670

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

The LCM of 635,842,640,670 is 2292664960.

Find LCM of 635,842,640,670 with Prime Factorization


2 635, 842, 640, 670
5 635, 421, 320, 335
127, 421, 64, 67

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

2 x 5 x 127 x 421 x 64 x 67 = 2292664960

Therefore, the lowest common multiple of 635,842,640,670 is 2292664960.

LCM Formula to Find Lowest Common Multiple of 635,842,640,670

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.

635 x 842 x 640 x 670 = 229266496000

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.

635 : 1, 5, 127, 635

842 : 1, 2, 421, 842

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

670 : 1, 2, 5, 10, 67, 134, 335, 670

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,842,640,670, is 1.

Now, the common factors can be found like this.

635:5x 127

842:2x 421

640:2x 2x 2x 2x 2x 2x 2x 5

670:2x 5x 67

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 5x 5 = 100

Therefore, the value for common factors is 100.

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 = 229266496000/(1x100)

LCM = 229266496000/100

LCM = 2292664960

Thus, we can understand that the LCM of 635,842,640,670 is 2292664960.
