Given numbers are 720,220,213,791,770

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

The LCM of 720,220,213,791,770 is 444795120.

Find LCM of 720,220,213,791,770 with Prime Factorization

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

2 x 2 x 3 x 5 x 7 x 11 x 12 x 1 x 71 x 113 x 1 = 444795120

Therefore, the lowest common multiple of 720,220,213,791,770 is 444795120.

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.

720 x 220 x 213 x 791 x 770 = 20549534544000

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.

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

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

213 : 1, 3, 71, 213

791 : 1, 7, 113, 791

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,220,213,791,770, is 1.

Now, the common factors can be found like this.

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

220:2x 2x 5x 11

213:3x 71

791:7x 113

770:2x 5x 7x 11

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 3x 5x 5x 7x 11 = 46200

Therefore, the value for common factors is 46200.

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 = 20549534544000/(1x46200)

LCM = 20549534544000/46200

LCM = 444795120

Thus, we can understand that the LCM of 720,220,213,791,770 is 444795120.
