Given numbers are 124,122,987,460

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

The LCM of 124,122,987,460 is 858551820.

Find LCM of 124,122,987,460 with Prime Factorization

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

2 x 2 x 31 x 61 x 987 x 115 = 858551820

Therefore, the lowest common multiple of 124,122,987,460 is 858551820.

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.

124 x 122 x 987 x 460 = 6868414560

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.

124 : 1, 2, 4, 31, 62, 124

122 : 1, 2, 61, 122

987 : 1, 3, 7, 21, 47, 141, 329, 987

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 124,122,987,460, is 1.

Now, the common factors can be found like this.

124:2x 2x 31

122:2x 61

987:3x 7x 47

460:2x 2x 5x 23

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 2 = 8

Therefore, the value for common factors is 8.

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 = 6868414560/(1x8)

LCM = 6868414560/8

LCM = 858551820

Thus, we can understand that the LCM of 124,122,987,460 is 858551820.
