Calculate the LCM of 920,397,738

Given numbers are 920,397,738

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

The LCM of 920,397,738 is 134773560.

Find LCM of 920,397,738 with Prime Factorization


2 920, 397, 738
460, 397, 369

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

2 x 460 x 397 x 369 = 134773560

Therefore, the lowest common multiple of 920,397,738 is 134773560.

LCM Formula to Find Lowest Common Multiple of 920,397,738

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.

920 x 397 x 738 = 269547120

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.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

397 : 1, 397

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,397,738, is 1.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

397:397

738:2x 3x 3x 41

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

2 = 2

Therefore, the value for common factors is 2.

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 = 269547120/(1x2)

LCM = 269547120/2

LCM = 134773560

Thus, we can understand that the LCM of 920,397,738 is 134773560.
