Calculate the LCM of 7,981,698,763

Given numbers are 7,981,698,763

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

The LCM of 7,981,698,763 is 4793166.

Find LCM of 7,981,698,763 with Prime Factorization


7 7, 981, 698, 763
109 1, 981, 698, 109
1, 9, 698, 1

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

7 x 109 x 1 x 9 x 698 x 1 = 4793166

Therefore, the lowest common multiple of 7,981,698,763 is 4793166.

LCM Formula to Find Lowest Common Multiple of 7,981,698,763

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.

7 x 981 x 698 x 763 = 3657185658

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.

7 : 1, 7

981 : 1, 3, 9, 109, 327, 981

698 : 1, 2, 349, 698

763 : 1, 7, 109, 763

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,981,698,763, is 1.

Now, the common factors can be found like this.

7:7

981:3x 3x 109

698:2x 349

763:7x 109

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

7x 109 = 763

Therefore, the value for common factors is 763.

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 = 3657185658/(1x763)

LCM = 3657185658/763

LCM = 4793166

Thus, we can understand that the LCM of 7,981,698,763 is 4793166.
