Given numbers are 427,622,721,39

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

The LCM of 427,622,721,39 is 1066891098.

Find LCM of 427,622,721,39 with Prime Factorization

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

7 x 61 x 622 x 103 x 39 = 1066891098

Therefore, the lowest common multiple of 427,622,721,39 is 1066891098.

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.

427 x 622 x 721 x 39 = 7468237686

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.

427 : 1, 7, 61, 427

622 : 1, 2, 311, 622

721 : 1, 7, 103, 721

39 : 1, 3, 13, 39

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,622,721,39, is 1.

Now, the common factors can be found like this.

427:7x 61

622:2x 311

721:7x 103

39:3x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

7 = 7

Therefore, the value for common factors is 7.

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 = 7468237686/(1x7)

LCM = 7468237686/7

LCM = 1066891098

Thus, we can understand that the LCM of 427,622,721,39 is 1066891098.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 971, 220, 805, 22
