Calculate the LCM of 640,673,665

Given numbers are 640,673,665

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

The LCM of 640,673,665 is 57285760.

Find LCM of 640,673,665 with Prime Factorization

5	640, 673, 665
	128, 673, 133

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

5 x 128 x 673 x 133 = 57285760

Therefore, the lowest common multiple of 640,673,665 is 57285760.

LCM Formula to Find Lowest Common Multiple of 640,673,665

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.

640 x 673 x 665 = 286428800

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.

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

673 : 1, 673

665 : 1, 5, 7, 19, 35, 95, 133, 665

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,673,665, is 1.

Now, the common factors can be found like this.

640:2x 2x 2x 2x 2x 2x 2x 5

673:673

665:5x 7x 19

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

5 = 5

Therefore, the value for common factors is 5.

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 = 286428800/(1x5)

LCM = 286428800/5

LCM = 57285760

Thus, we can understand that the LCM of 640,673,665 is 57285760.
