Given numbers are 79,42,76,19,874

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

The LCM of 79,42,76,19,874 is 2899932.

Find LCM of 79,42,76,19,874 with Prime Factorization

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

2 x 19 x 79 x 21 x 2 x 1 x 23 = 2899932

Therefore, the lowest common multiple of 79,42,76,19,874 is 2899932.

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.

79 x 42 x 76 x 19 x 874 = 4187501808

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.

79 : 1, 79

42 : 1, 2, 3, 6, 7, 14, 21, 42

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

19 : 1, 19

874 : 1, 2, 19, 23, 38, 46, 437, 874

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 79,42,76,19,874, is 1.

Now, the common factors can be found like this.

79:79

42:2x 3x 7

76:2x 2x 19

19:19

874:2x 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 = 4187501808/(1x1444)

LCM = 4187501808/1444

LCM = 2899932

Thus, we can understand that the LCM of 79,42,76,19,874 is 2899932.
