Given numbers are 644,519,865,769

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

The LCM of 644,519,865,769 is 1285137420.

Find LCM of 644,519,865,769 with Prime Factorization

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

173 x 644 x 3 x 5 x 769 = 1285137420

Therefore, the lowest common multiple of 644,519,865,769 is 1285137420.

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.

644 x 519 x 865 x 769 = 222328773660

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

519 : 1, 3, 173, 519

865 : 1, 5, 173, 865

769 : 1, 769

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,519,865,769, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

519:3x 173

865:5x 173

769:769

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

173 = 173

Therefore, the value for common factors is 173.

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 = 222328773660/(1x173)

LCM = 222328773660/173

LCM = 1285137420

Thus, we can understand that the LCM of 644,519,865,769 is 1285137420.
