Calculate the LCM of 690,737,745,506

Given numbers are 690,737,745,506

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

The LCM of 690,737,745,506 is 75770970.

Find LCM of 690,737,745,506 with Prime Factorization


2 690, 737, 745, 506
5 345, 737, 745, 253
11 69, 737, 149, 253
23 69, 67, 149, 23
3, 67, 149, 1

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

2 x 5 x 11 x 23 x 3 x 67 x 149 x 1 = 75770970

Therefore, the lowest common multiple of 690,737,745,506 is 75770970.

LCM Formula to Find Lowest Common Multiple of 690,737,745,506

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.

690 x 737 x 745 x 506 = 191700554100

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

737 : 1, 11, 67, 737

745 : 1, 5, 149, 745

506 : 1, 2, 11, 22, 23, 46, 253, 506

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,737,745,506, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

737:11x 67

745:5x 149

506:2x 11x 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 5x 11x 23 = 2530

Therefore, the value for common factors is 2530.

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 = 191700554100/(1x2530)

LCM = 191700554100/2530

LCM = 75770970

Thus, we can understand that the LCM of 690,737,745,506 is 75770970.
