Given numbers are 623,228,199,987

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

The LCM of 623,228,199,987 is 1328537532.

Find LCM of 623,228,199,987 with Prime Factorization

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

3 x 7 x 89 x 76 x 199 x 47 = 1328537532

Therefore, the lowest common multiple of 623,228,199,987 is 1328537532.

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.

623 x 228 x 199 x 987 = 27899288172

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.

623 : 1, 7, 89, 623

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

199 : 1, 199

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,228,199,987, is 1.

Now, the common factors can be found like this.

623:7x 89

228:2x 2x 3x 19

199:199

987:3x 7x 47

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 27899288172/(1x21)

LCM = 27899288172/21

LCM = 1328537532

Thus, we can understand that the LCM of 623,228,199,987 is 1328537532.
