Find LCM of 868,713,147,560 with Prime Factorization
2 | 868, 713, 147, 560 |
2 | 434, 713, 147, 280 |
7 | 217, 713, 147, 140 |
31 | 31, 713, 21, 20 |
1, 23, 21, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 31 x 1 x 23 x 21 x 20 = 8384880
Therefore, the lowest common multiple of 868,713,147,560 is 8384880.
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.
868 x 713 x 147 x 560 = 50946530880
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.
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
713 : 1, 23, 31, 713
147 : 1, 3, 7, 21, 49, 147
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,713,147,560, is 1.
Now, the common factors can be found like this.
868:2x 2x 7x 31
713:23x 31
147:3x 7x 7
560:2x 2x 2x 2x 5x 7
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 7x 7x 31 = 6076
Therefore, the value for common factors is 6076.
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 = 50946530880/(1x6076)
LCM = 50946530880/6076
LCM = 8384880
Thus, we can understand that the LCM of 868,713,147,560 is 8384880.
