Given numbers are 669,856,145,812

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

The LCM of 669,856,145,812 is 581253960.

Find LCM of 669,856,145,812 with Prime Factorization

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

2 x 2 x 29 x 669 x 214 x 5 x 7 = 581253960

Therefore, the lowest common multiple of 669,856,145,812 is 581253960.

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.

669 x 856 x 145 x 812 = 67425459360

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.

669 : 1, 3, 223, 669

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

145 : 1, 5, 29, 145

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 669,856,145,812, is 1.

Now, the common factors can be found like this.

669:3x 223

856:2x 2x 2x 107

145:5x 29

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 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 = 67425459360/(1x116)

LCM = 67425459360/116

LCM = 581253960

Thus, we can understand that the LCM of 669,856,145,812 is 581253960.
