Given numbers are 780,748,980,332,720

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

The LCM of 780,748,980,332,720 is 7118551440.

Find LCM of 780,748,980,332,720 with Prime Factorization

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

2 x 2 x 3 x 5 x 13 x 187 x 49 x 83 x 12 = 7118551440

Therefore, the lowest common multiple of 780,748,980,332,720 is 7118551440.

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.

780 x 748 x 980 x 332 x 720 = 136676187648000

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.

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

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

332 : 1, 2, 4, 83, 166, 332

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,748,980,332,720, is 4.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

748:2x 2x 11x 17

980:2x 2x 5x 7x 7

332:2x 2x 83

720:2x 2x 2x 2x 3x 3x 5

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 2x 2x 3x 5x 5 = 4800

Therefore, the value for common factors is 4800.

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 = 136676187648000/(4x4800)

LCM = 136676187648000/19200

LCM = 7118551440

Thus, we can understand that the LCM of 780,748,980,332,720 is 7118551440.
