Given numbers are 945,473,902,868,154

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

The LCM of 945,473,902,868,154 is 2272471740.

Find LCM of 945,473,902,868,154 with Prime Factorization

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

2 x 7 x 11 x 135 x 43 x 41 x 62 x 1 = 2272471740

Therefore, the lowest common multiple of 945,473,902,868,154 is 2272471740.

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.

945 x 473 x 902 x 868 x 154 = 53893939785840

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.

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

473 : 1, 11, 43, 473

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

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

154 : 1, 2, 7, 11, 14, 22, 77, 154

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,473,902,868,154, is 1.

Now, the common factors can be found like this.

945:3x 3x 3x 5x 7

473:11x 43

902:2x 11x 41

868:2x 2x 7x 31

154:2x 7x 11

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 7x 7x 11x 11 = 23716

Therefore, the value for common factors is 23716.

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 = 53893939785840/(1x23716)

LCM = 53893939785840/23716

LCM = 2272471740

Thus, we can understand that the LCM of 945,473,902,868,154 is 2272471740.
