Calculate the LCM of 456,438,621,470,605

Given numbers are 456,438,621,470,605

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

The LCM of 456,438,621,470,605 is 195934665960.

Find LCM of 456,438,621,470,605 with Prime Factorization


2 456, 438, 621, 470, 605
3 228, 219, 621, 235, 605
5 76, 73, 207, 235, 605
76, 73, 207, 47, 121

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

2 x 3 x 5 x 76 x 73 x 207 x 47 x 121 = 195934665960

Therefore, the lowest common multiple of 456,438,621,470,605 is 195934665960.

LCM Formula to Find Lowest Common Multiple of 456,438,621,470,605

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.

456 x 438 x 621 x 470 x 605 = 35268239872800

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.

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

438 : 1, 2, 3, 6, 73, 146, 219, 438

621 : 1, 3, 9, 23, 27, 69, 207, 621

470 : 1, 2, 5, 10, 47, 94, 235, 470

605 : 1, 5, 11, 55, 121, 605

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,438,621,470,605, is 1.

Now, the common factors can be found like this.

456:2x 2x 2x 3x 19

438:2x 3x 73

621:3x 3x 3x 23

470:2x 5x 47

605:5x 11x 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 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 35268239872800/(1x180)

LCM = 35268239872800/180

LCM = 195934665960

Thus, we can understand that the LCM of 456,438,621,470,605 is 195934665960.
