Given numbers are 287,182,515,121,774

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

The LCM of 287,182,515,121,774 is 179952883110.

Find LCM of 287,182,515,121,774 with Prime Factorization

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

2 x 7 x 41 x 13 x 515 x 121 x 387 = 179952883110

Therefore, the lowest common multiple of 287,182,515,121,774 is 179952883110.

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.

287 x 182 x 515 x 121 x 774 = 2519340363540

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.

287 : 1, 7, 41, 287

182 : 1, 2, 7, 13, 14, 26, 91, 182

515 : 1, 5, 103, 515

121 : 1, 11, 121

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,182,515,121,774, is 1.

Now, the common factors can be found like this.

287:7x 41

182:2x 7x 13

515:5x 103

121:11x 11

774:2x 3x 3x 43

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 2519340363540/(1x14)

LCM = 2519340363540/14

LCM = 179952883110

Thus, we can understand that the LCM of 287,182,515,121,774 is 179952883110.
