Given numbers are 530,104,780,107,890

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

The LCM of 530,104,780,107,890 is 787361640.

Find LCM of 530,104,780,107,890 with Prime Factorization

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

2 x 2 x 5 x 13 x 53 x 2 x 3 x 107 x 89 = 787361640

Therefore, the lowest common multiple of 530,104,780,107,890 is 787361640.

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.

530 x 104 x 780 x 107 x 890 = 4094280528000

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.

530 : 1, 2, 5, 10, 53, 106, 265, 530

104 : 1, 2, 4, 8, 13, 26, 52, 104

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

107 : 1, 107

890 : 1, 2, 5, 10, 89, 178, 445, 890

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 530,104,780,107,890, is 1.

Now, the common factors can be found like this.

530:2x 5x 53

104:2x 2x 2x 13

780:2x 2x 3x 5x 13

107:107

890:2x 5x 89

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 5x 5x 13 = 5200

Therefore, the value for common factors is 5200.

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 = 4094280528000/(1x5200)

LCM = 4094280528000/5200

LCM = 787361640

Thus, we can understand that the LCM of 530,104,780,107,890 is 787361640.
