Find LCM of 748,858,963,689 with Prime Factorization


2 748, 858, 963, 689
3 374, 429, 963, 689
11 374, 143, 321, 689
13 34, 13, 321, 689
34, 1, 321, 53

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

2 x 3 x 11 x 13 x 34 x 1 x 321 x 53 = 496303236

Therefore, the lowest common multiple of 748,858,963,689 is 496303236.

LCM Formula to Find Lowest Common Multiple of 748,858,963,689

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.

748 x 858 x 963 x 689 = 425828176488

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.

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

963 : 1, 3, 9, 107, 321, 963

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,858,963,689, is 1.

Now, the common factors can be found like this.

748:2x 2x 11x 17

858:2x 3x 11x 13

963:3x 3x 107

689:13x 53

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 11x 13 = 858

Therefore, the value for common factors is 858.

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 = 425828176488/(1x858)

LCM = 425828176488/858

LCM = 496303236

Thus, we can understand that the LCM of 748,858,963,689 is 496303236.
