The LCM of 650,667,207,690 is 3901950.

Find LCM of 650,667,207,690 with Prime Factorization


2 650, 667, 207, 690
3 325, 667, 207, 345
5 325, 667, 69, 115
23 65, 667, 69, 23
65, 29, 3, 1

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

2 x 3 x 5 x 23 x 65 x 29 x 3 x 1 = 3901950

Therefore, the lowest common multiple of 650,667,207,690 is 3901950.

LCM Formula to Find Lowest Common Multiple of 650,667,207,690

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.

650 x 667 x 207 x 690 = 61923946500

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.

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

667 : 1, 23, 29, 667

207 : 1, 3, 9, 23, 69, 207

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 650,667,207,690, is 1.

Now, the common factors can be found like this.

650:2x 5x 5x 13

667:23x 29

207:3x 3x 23

690:2x 3x 5x 23

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 5x 23x 23 = 15870

Therefore, the value for common factors is 15870.

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 = 61923946500/(1x15870)

LCM = 61923946500/15870

LCM = 3901950

Thus, we can understand that the LCM of 650,667,207,690 is 3901950.
