Find LCM of 639,335,870,349,764 with Prime Factorization


2 639, 335, 870, 349, 764
3 639, 335, 435, 349, 382
5 213, 335, 145, 349, 382
213, 67, 29, 349, 382

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

2 x 3 x 5 x 213 x 67 x 29 x 349 x 382 = 1655245624860

Therefore, the lowest common multiple of 639,335,870,349,764 is 1655245624860.

LCM Formula to Find Lowest Common Multiple of 639,335,870,349,764

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.

639 x 335 x 870 x 349 x 764 = 49657368745800

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.

639 : 1, 3, 9, 71, 213, 639

335 : 1, 5, 67, 335

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

349 : 1, 349

764 : 1, 2, 4, 191, 382, 764

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,335,870,349,764, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

335:5x 67

870:2x 3x 5x 29

349:349

764:2x 2x 191

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

2x 3x 5 = 30

Therefore, the value for common factors is 30.

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 = 49657368745800/(1x30)

LCM = 49657368745800/30

LCM = 1655245624860

Thus, we can understand that the LCM of 639,335,870,349,764 is 1655245624860.
