Given numbers are 817,357,649,970,655

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

The LCM of 817,357,649,970,655 is 24053484509670.

Find LCM of 817,357,649,970,655 with Prime Factorization

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

5 x 817 x 357 x 649 x 194 x 131 = 24053484509670

Therefore, the lowest common multiple of 817,357,649,970,655 is 24053484509670.

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.

817 x 357 x 649 x 970 x 655 = 120267422548350

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.

817 : 1, 19, 43, 817

357 : 1, 3, 7, 17, 21, 51, 119, 357

649 : 1, 11, 59, 649

970 : 1, 2, 5, 10, 97, 194, 485, 970

655 : 1, 5, 131, 655

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,357,649,970,655, is 1.

Now, the common factors can be found like this.

817:19x 43

357:3x 7x 17

649:11x 59

970:2x 5x 97

655:5x 131

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

5 = 5

Therefore, the value for common factors is 5.

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 = 120267422548350/(1x5)

LCM = 120267422548350/5

LCM = 24053484509670

Thus, we can understand that the LCM of 817,357,649,970,655 is 24053484509670.
