Find LCM of 975,854,706,427,420 with Prime Factorization
| 2 | 975, 854, 706, 427, 420 |
| 3 | 975, 427, 353, 427, 210 |
| 5 | 325, 427, 353, 427, 70 |
| 7 | 65, 427, 353, 427, 14 |
| 61 | 65, 61, 353, 61, 2 |
| 65, 1, 353, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 61 x 65 x 1 x 353 x 1 x 2 = 587850900
Therefore, the lowest common multiple of 975,854,706,427,420 is 587850900.
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.
975 x 854 x 706 x 427 x 420 = 105425180406000
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.
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
854 : 1, 2, 7, 14, 61, 122, 427, 854
706 : 1, 2, 353, 706
427 : 1, 7, 61, 427
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 975,854,706,427,420, is 1.
Now, the common factors can be found like this.
975:3x 5x 5x 13
854:2x 7x 61
706:2x 353
427:7x 61
420:2x 2x 3x 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 3x 5x 7x 7x 61 = 179340
Therefore, the value for common factors is 179340.
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 = 105425180406000/(1x179340)
LCM = 105425180406000/179340
LCM = 587850900
Thus, we can understand that the LCM of 975,854,706,427,420 is 587850900.
