Given numbers are 65,43,43,770

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

The LCM of 65,43,43,770 is 430430.

Find LCM of 65,43,43,770 with Prime Factorization

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

5 x 43 x 13 x 1 x 1 x 154 = 430430

Therefore, the lowest common multiple of 65,43,43,770 is 430430.

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.

65 x 43 x 43 x 770 = 92542450

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.

65 : 1, 5, 13, 65

43 : 1, 43

43 : 1, 43

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 65,43,43,770, is 1.

Now, the common factors can be found like this.

65:5x 13

43:43

43:43

770:2x 5x 7x 11

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

5x 43 = 215

Therefore, the value for common factors is 215.

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 = 92542450/(1x215)

LCM = 92542450/215

LCM = 430430

Thus, we can understand that the LCM of 65,43,43,770 is 430430.

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