Given numbers are 220,700,840,544

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

The LCM of 220,700,840,544 is 3141600.

Find LCM of 220,700,840,544 with Prime Factorization

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

2 x 2 x 2 x 5 x 7 x 11 x 5 x 3 x 68 = 3141600

Therefore, the lowest common multiple of 220,700,840,544 is 3141600.

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.

220 x 700 x 840 x 544 = 70371840000

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.

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

700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700

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

544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,700,840,544, is 4.

Now, the common factors can be found like this.

220:2x 2x 5x 11

700:2x 2x 5x 5x 7

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

544:2x 2x 2x 2x 2x 17

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 5x 5x 7 = 5600

Therefore, the value for common factors is 5600.

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 = 70371840000/(4x5600)

LCM = 70371840000/22400

LCM = 3141600

Thus, we can understand that the LCM of 220,700,840,544 is 3141600.
