The LCM of 695,261,278,812 is 5079060.

Find LCM of 695,261,278,812 with Prime Factorization


2 695, 261, 278, 812
29 695, 261, 139, 406
139 695, 9, 139, 14
5, 9, 1, 14

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

2 x 29 x 139 x 5 x 9 x 1 x 14 = 5079060

Therefore, the lowest common multiple of 695,261,278,812 is 5079060.

LCM Formula to Find Lowest Common Multiple of 695,261,278,812

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.

695 x 261 x 278 x 812 = 40947381720

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.

695 : 1, 5, 139, 695

261 : 1, 3, 9, 29, 87, 261

278 : 1, 2, 139, 278

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 695,261,278,812, is 1.

Now, the common factors can be found like this.

695:5x 139

261:3x 3x 29

278:2x 139

812:2x 2x 7x 29

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

2x 29x 139 = 8062

Therefore, the value for common factors is 8062.

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 = 40947381720/(1x8062)

LCM = 40947381720/8062

LCM = 5079060

Thus, we can understand that the LCM of 695,261,278,812 is 5079060.
