Given numbers are 787,638,546,780

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

The LCM of 787,638,546,780 is 1370749380.

Find LCM of 787,638,546,780 with Prime Factorization

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

2 x 3 x 13 x 787 x 319 x 7 x 10 = 1370749380

Therefore, the lowest common multiple of 787,638,546,780 is 1370749380.

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.

787 x 638 x 546 x 780 = 213836903280

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.

787 : 1, 787

638 : 1, 2, 11, 22, 29, 58, 319, 638

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,638,546,780, is 1.

Now, the common factors can be found like this.

787:787

638:2x 11x 29

546:2x 3x 7x 13

780:2x 2x 3x 5x 13

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 3x 13 = 156

Therefore, the value for common factors is 156.

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 = 213836903280/(1x156)

LCM = 213836903280/156

LCM = 1370749380

Thus, we can understand that the LCM of 787,638,546,780 is 1370749380.
