Find LCM of 711,720,987,752 with Prime Factorization
2 | 711, 720, 987, 752 |
2 | 711, 360, 987, 376 |
2 | 711, 180, 987, 188 |
2 | 711, 90, 987, 94 |
3 | 711, 45, 987, 47 |
3 | 237, 15, 329, 47 |
47 | 79, 5, 329, 47 |
79, 5, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 47 x 79 x 5 x 7 x 1 = 18713520
Therefore, the lowest common multiple of 711,720,987,752 is 18713520.
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.
711 x 720 x 987 x 752 = 379959310080
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.
711 : 1, 3, 9, 79, 237, 711
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
987 : 1, 3, 7, 21, 47, 141, 329, 987
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 711,720,987,752, is 1.
Now, the common factors can be found like this.
711:3x 3x 79
720:2x 2x 2x 2x 3x 3x 5
987:3x 7x 47
752:2x 2x 2x 2x 47
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 3x 3x 3x 47 = 20304
Therefore, the value for common factors is 20304.
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 = 379959310080/(1x20304)
LCM = 379959310080/20304
LCM = 18713520
Thus, we can understand that the LCM of 711,720,987,752 is 18713520.
