Given numbers are 660,386,220,603,107

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

The LCM of 660,386,220,603,107 is 2739561660.

Find LCM of 660,386,220,603,107 with Prime Factorization

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

2 x 2 x 3 x 5 x 11 x 1 x 193 x 1 x 201 x 107 = 2739561660

Therefore, the lowest common multiple of 660,386,220,603,107 is 2739561660.

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.

660 x 386 x 220 x 603 x 107 = 3616221391200

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

386 : 1, 2, 193, 386

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

603 : 1, 3, 9, 67, 201, 603

107 : 1, 107

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,386,220,603,107, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

386:2x 193

220:2x 2x 5x 11

603:3x 3x 67

107:107

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 11 = 1320

Therefore, the value for common factors is 1320.

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 = 3616221391200/(1x1320)

LCM = 3616221391200/1320

LCM = 2739561660

Thus, we can understand that the LCM of 660,386,220,603,107 is 2739561660.
