Given numbers are 650,840,780,580

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

The LCM of 650,840,780,580 is 1583400.

Find LCM of 650,840,780,580 with Prime Factorization

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

2 x 2 x 3 x 5 x 13 x 1 x 14 x 5 x 29 = 1583400

Therefore, the lowest common multiple of 650,840,780,580 is 1583400.

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.

650 x 840 x 780 x 580 = 247010400000

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.

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

10 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 650,840,780,580, is 10.

Now, the common factors can be found like this.

650:2x 5x 5x 13

840:2x 2x 2x 3x 5x 7

780:2x 2x 3x 5x 13

580:2x 2x 5x 29

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 2x 2x 3x 5x 5x 13 = 15600

Therefore, the value for common factors is 15600.

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 = 247010400000/(10x15600)

LCM = 247010400000/156000

LCM = 1583400

Thus, we can understand that the LCM of 650,840,780,580 is 1583400.
