Calculate the LCM of 76,20,57,437

Given numbers are 76,20,57,437

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

The LCM of 76,20,57,437 is 26220.

Find LCM of 76,20,57,437 with Prime Factorization


2 76, 20, 57, 437
2 38, 10, 57, 437
19 19, 5, 57, 437
1, 5, 3, 23

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

2 x 2 x 19 x 1 x 5 x 3 x 23 = 26220

Therefore, the lowest common multiple of 76,20,57,437 is 26220.

LCM Formula to Find Lowest Common Multiple of 76,20,57,437

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.

76 x 20 x 57 x 437 = 37861680

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.

76 : 1, 2, 4, 19, 38, 76

20 : 1, 2, 4, 5, 10, 20

57 : 1, 3, 19, 57

437 : 1, 19, 23, 437

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 76,20,57,437, is 1.

Now, the common factors can be found like this.

76:2x 2x 19

20:2x 2x 5

57:3x 19

437:19x 23

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 19x 19 = 1444

Therefore, the value for common factors is 1444.

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 = 37861680/(1x1444)

LCM = 37861680/1444

LCM = 26220

Thus, we can understand that the LCM of 76,20,57,437 is 26220.
