Find LCM of 968,744,689,520,921 with Prime Factorization
2 | 968, 744, 689, 520, 921 |
2 | 484, 372, 689, 260, 921 |
2 | 242, 186, 689, 130, 921 |
3 | 121, 93, 689, 65, 921 |
13 | 121, 31, 689, 65, 307 |
121, 31, 53, 5, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 121 x 31 x 53 x 5 x 307 = 95210732760
Therefore, the lowest common multiple of 968,744,689,520,921 is 95210732760.
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.
968 x 744 x 689 x 520 x 921 = 237645988968960
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.
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
689 : 1, 13, 53, 689
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 968,744,689,520,921, is 1.
Now, the common factors can be found like this.
968:2x 2x 2x 11x 11
744:2x 2x 2x 3x 31
689:13x 53
520:2x 2x 2x 5x 13
921:3x 307
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 2x 3x 13 = 2496
Therefore, the value for common factors is 2496.
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 = 237645988968960/(1x2496)
LCM = 237645988968960/2496
LCM = 95210732760
Thus, we can understand that the LCM of 968,744,689,520,921 is 95210732760.
