Find LCM of 972,185,903,450,280 with Prime Factorization
| 2 | 972, 185, 903, 450, 280 |
| 2 | 486, 185, 903, 225, 140 |
| 3 | 243, 185, 903, 225, 70 |
| 3 | 81, 185, 301, 75, 70 |
| 5 | 27, 185, 301, 25, 70 |
| 7 | 27, 37, 301, 5, 14 |
| 27, 37, 43, 5, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 7 x 27 x 37 x 43 x 5 x 2 = 541258200
Therefore, the lowest common multiple of 972,185,903,450,280 is 541258200.
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.
972 x 185 x 903 x 450 x 280 = 20459559960000
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
185 : 1, 5, 37, 185
903 : 1, 3, 7, 21, 43, 129, 301, 903
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,185,903,450,280, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
185:5x 37
903:3x 7x 43
450:2x 3x 3x 5x 5
280:2x 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 2x 3x 3x 3x 5x 5x 7 = 37800
Therefore, the value for common factors is 37800.
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 = 20459559960000/(1x37800)
LCM = 20459559960000/37800
LCM = 541258200
Thus, we can understand that the LCM of 972,185,903,450,280 is 541258200.
