Calculate the LCM of 90,79,79,13,514

Given numbers are 90,79,79,13,514

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

The LCM of 90,79,79,13,514 is 23754510.

Find LCM of 90,79,79,13,514 with Prime Factorization


2 90, 79, 79, 13, 514
79 45, 79, 79, 13, 257
45, 1, 1, 13, 257

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

2 x 79 x 45 x 1 x 1 x 13 x 257 = 23754510

Therefore, the lowest common multiple of 90,79,79,13,514 is 23754510.

LCM Formula to Find Lowest Common Multiple of 90,79,79,13,514

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.

90 x 79 x 79 x 13 x 514 = 3753212580

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.

90 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

79 : 1, 79

79 : 1, 79

13 : 1, 13

514 : 1, 2, 257, 514

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 90,79,79,13,514, is 1.

Now, the common factors can be found like this.

90:2x 3x 3x 5

79:79

79:79

13:13

514:2x 257

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

2x 79 = 158

Therefore, the value for common factors is 158.

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 = 3753212580/(1x158)

LCM = 3753212580/158

LCM = 23754510

Thus, we can understand that the LCM of 90,79,79,13,514 is 23754510.
