Given numbers are 217,407,527,775,686

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

The LCM of 217,407,527,775,686 is 3678486350.

Find LCM of 217,407,527,775,686 with Prime Factorization

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

7 x 31 x 1 x 407 x 17 x 25 x 98 = 3678486350

Therefore, the lowest common multiple of 217,407,527,775,686 is 3678486350.

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.

217 x 407 x 527 x 775 x 686 = 24745177676450

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.

217 : 1, 7, 31, 217

407 : 1, 11, 37, 407

527 : 1, 17, 31, 527

775 : 1, 5, 25, 31, 155, 775

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,407,527,775,686, is 1.

Now, the common factors can be found like this.

217:7x 31

407:11x 37

527:17x 31

775:5x 5x 31

686:2x 7x 7x 7

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

7x 31x 31 = 6727

Therefore, the value for common factors is 6727.

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 = 24745177676450/(1x6727)

LCM = 24745177676450/6727

LCM = 3678486350

Thus, we can understand that the LCM of 217,407,527,775,686 is 3678486350.
