Find LCM of 816,728,724,697 with Prime Factorization


2 816, 728, 724, 697
2 408, 364, 362, 697
2 204, 182, 181, 697
17 102, 91, 181, 697
6, 91, 181, 41

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

2 x 2 x 2 x 17 x 6 x 91 x 181 x 41 = 551053776

Therefore, the lowest common multiple of 816,728,724,697 is 551053776.

LCM Formula to Find Lowest Common Multiple of 816,728,724,697

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.

816 x 728 x 724 x 697 = 299773254144

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.

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

724 : 1, 2, 4, 181, 362, 724

697 : 1, 17, 41, 697

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,728,724,697, is 1.

Now, the common factors can be found like this.

816:2x 2x 2x 2x 3x 17

728:2x 2x 2x 7x 13

724:2x 2x 181

697:17x 41

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 2x 17 = 544

Therefore, the value for common factors is 544.

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 = 299773254144/(1x544)

LCM = 299773254144/544

LCM = 551053776

Thus, we can understand that the LCM of 816,728,724,697 is 551053776.
