Given numbers are 902,153,121,644

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

The LCM of 902,153,121,644 is 488817252.

Find LCM of 902,153,121,644 with Prime Factorization

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

2 x 11 x 41 x 153 x 11 x 322 = 488817252

Therefore, the lowest common multiple of 902,153,121,644 is 488817252.

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.

902 x 153 x 121 x 644 = 10753979544

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.

902 : 1, 2, 11, 22, 41, 82, 451, 902

153 : 1, 3, 9, 17, 51, 153

121 : 1, 11, 121

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,153,121,644, is 1.

Now, the common factors can be found like this.

902:2x 11x 41

153:3x 3x 17

121:11x 11

644:2x 2x 7x 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 11 = 22

Therefore, the value for common factors is 22.

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 = 10753979544/(1x22)

LCM = 10753979544/22

LCM = 488817252

Thus, we can understand that the LCM of 902,153,121,644 is 488817252.
