The LCM of 716,639,856,387 is 4210135848.

Find LCM of 716,639,856,387 with Prime Factorization


2 716, 639, 856, 387
2 358, 639, 428, 387
3 179, 639, 214, 387
3 179, 213, 214, 129
179, 71, 214, 43

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

2 x 2 x 3 x 3 x 179 x 71 x 214 x 43 = 4210135848

Therefore, the lowest common multiple of 716,639,856,387 is 4210135848.

LCM Formula to Find Lowest Common Multiple of 716,639,856,387

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.

716 x 639 x 856 x 387 = 151564890528

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.

716 : 1, 2, 4, 179, 358, 716

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

856 : 1, 2, 4, 8, 107, 214, 428, 856

387 : 1, 3, 9, 43, 129, 387

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 716,639,856,387, is 1.

Now, the common factors can be found like this.

716:2x 2x 179

639:3x 3x 71

856:2x 2x 2x 107

387:3x 3x 43

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 151564890528/(1x36)

LCM = 151564890528/36

LCM = 4210135848

Thus, we can understand that the LCM of 716,639,856,387 is 4210135848.
