Find LCM of 920,700,210,975,125 with Prime Factorization
| 2 | 920, 700, 210, 975, 125 |
| 2 | 460, 350, 105, 975, 125 |
| 3 | 230, 175, 105, 975, 125 |
| 5 | 230, 175, 35, 325, 125 |
| 5 | 46, 7, 35, 65, 25 |
| 7 | 46, 7, 7, 13, 5 |
| 46, 1, 1, 13, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 5 x 7 x 46 x 1 x 1 x 13 x 5 = 6279000
Therefore, the lowest common multiple of 920,700,210,975,125 is 6279000.
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.
920 x 700 x 210 x 975 x 125 = 16482375000000
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
125 : 1, 5, 25, 125
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,700,210,975,125, is 5.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
700:2x 2x 5x 5x 7
210:2x 3x 5x 7
975:3x 5x 5x 13
125:5x 5x 5
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 3x 5x 5x 5x 5x 5x 7 = 525000
Therefore, the value for common factors is 525000.
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 = 16482375000000/(5x525000)
LCM = 16482375000000/2625000
LCM = 6279000
Thus, we can understand that the LCM of 920,700,210,975,125 is 6279000.
