The LCM of 748,736,621,988 is 917867808.

Find LCM of 748,736,621,988 with Prime Factorization


2 748, 736, 621, 988
2 374, 368, 621, 494
23 187, 184, 621, 247
187, 8, 27, 247

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

2 x 2 x 23 x 187 x 8 x 27 x 247 = 917867808

Therefore, the lowest common multiple of 748,736,621,988 is 917867808.

LCM Formula to Find Lowest Common Multiple of 748,736,621,988

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 736 x 621 x 988 = 337775353344

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

736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736

621 : 1, 3, 9, 23, 27, 69, 207, 621

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,736,621,988, is 1.

Now, the common factors can be found like this.

748:2x 2x 11x 17

736:2x 2x 2x 2x 2x 23

621:3x 3x 3x 23

988:2x 2x 13x 19

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

2x 2x 2x 2x 23 = 368

Therefore, the value for common factors is 368.

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 = 337775353344/(1x368)

LCM = 337775353344/368

LCM = 917867808

Thus, we can understand that the LCM of 748,736,621,988 is 917867808.
