Calculate the LCM of 690,723,370,143

Given numbers are 690,723,370,143

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

The LCM of 690,723,370,143 is 879840390.

Find LCM of 690,723,370,143 with Prime Factorization


2 690, 723, 370, 143
3 345, 723, 185, 143
5 115, 241, 185, 143
23, 241, 37, 143

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

2 x 3 x 5 x 23 x 241 x 37 x 143 = 879840390

Therefore, the lowest common multiple of 690,723,370,143 is 879840390.

LCM Formula to Find Lowest Common Multiple of 690,723,370,143

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 723 x 370 x 143 = 26395211700

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

723 : 1, 3, 241, 723

370 : 1, 2, 5, 10, 37, 74, 185, 370

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,723,370,143, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

723:3x 241

370:2x 5x 37

143:11x 13

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

2x 3x 5 = 30

Therefore, the value for common factors is 30.

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 = 26395211700/(1x30)

LCM = 26395211700/30

LCM = 879840390

Thus, we can understand that the LCM of 690,723,370,143 is 879840390.
