Given numbers are 669,862,170,136

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

The LCM of 669,862,170,136 is 196070520.

Find LCM of 669,862,170,136 with Prime Factorization

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

2 x 17 x 669 x 431 x 5 x 4 = 196070520

Therefore, the lowest common multiple of 669,862,170,136 is 196070520.

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 862 x 170 x 136 = 13332795360

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

862 : 1, 2, 431, 862

170 : 1, 2, 5, 10, 17, 34, 85, 170

136 : 1, 2, 4, 8, 17, 34, 68, 136

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,862,170,136, is 1.

Now, the common factors can be found like this.

669:3x 223

862:2x 431

170:2x 5x 17

136:2x 2x 2x 17

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 17 = 68

Therefore, the value for common factors is 68.

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 = 13332795360/(1x68)

LCM = 13332795360/68

LCM = 196070520

Thus, we can understand that the LCM of 669,862,170,136 is 196070520.
