Given numbers are 654,674,987,919

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

The LCM of 654,674,987,919 is 66637555698.

Find LCM of 654,674,987,919 with Prime Factorization

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

2 x 3 x 109 x 337 x 329 x 919 = 66637555698

Therefore, the lowest common multiple of 654,674,987,919 is 66637555698.

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.

654 x 674 x 987 x 919 = 399825334188

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.

654 : 1, 2, 3, 6, 109, 218, 327, 654

674 : 1, 2, 337, 674

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

919 : 1, 919

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,674,987,919, is 1.

Now, the common factors can be found like this.

654:2x 3x 109

674:2x 337

987:3x 7x 47

919:919

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 399825334188/(1x6)

LCM = 399825334188/6

LCM = 66637555698

Thus, we can understand that the LCM of 654,674,987,919 is 66637555698.
