Given numbers are 74,65,67,91,557

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

The LCM of 74,65,67,91,557 is 1256530730.

Find LCM of 74,65,67,91,557 with Prime Factorization

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

13 x 74 x 5 x 67 x 7 x 557 = 1256530730

Therefore, the lowest common multiple of 74,65,67,91,557 is 1256530730.

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.

74 x 65 x 67 x 91 x 557 = 16334899490

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.

74 : 1, 2, 37, 74

65 : 1, 5, 13, 65

67 : 1, 67

91 : 1, 7, 13, 91

557 : 1, 557

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 74,65,67,91,557, is 1.

Now, the common factors can be found like this.

74:2x 37

65:5x 13

67:67

91:7x 13

557:557

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

13 = 13

Therefore, the value for common factors is 13.

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 = 16334899490/(1x13)

LCM = 16334899490/13

LCM = 1256530730

Thus, we can understand that the LCM of 74,65,67,91,557 is 1256530730.

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