Given numbers are 961,903,551,217

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

The LCM of 961,903,551,217 is 478148433.

Find LCM of 961,903,551,217 with Prime Factorization

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

7 x 31 x 1 x 129 x 551 x 31 = 478148433

Therefore, the lowest common multiple of 961,903,551,217 is 478148433.

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.

961 x 903 x 551 x 217 = 103758209961

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.

961 : 1, 31, 961

903 : 1, 3, 7, 21, 43, 129, 301, 903

551 : 1, 19, 29, 551

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,903,551,217, is 1.

Now, the common factors can be found like this.

961:31x 31

903:3x 7x 43

551:19x 29

217:7x 31

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

7x 31 = 217

Therefore, the value for common factors is 217.

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 = 103758209961/(1x217)

LCM = 103758209961/217

LCM = 478148433

Thus, we can understand that the LCM of 961,903,551,217 is 478148433.
