Given numbers are 272,909,974,420,350
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 272,909,974,420,350 is 21071710800.
Find LCM of 272,909,974,420,350 with Prime Factorization
| 2 | 272, 909, 974, 420, 350 |
| 2 | 136, 909, 487, 210, 175 |
| 3 | 68, 909, 487, 105, 175 |
| 5 | 68, 303, 487, 35, 175 |
| 7 | 68, 303, 487, 7, 35 |
| 68, 303, 487, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 68 x 303 x 487 x 1 x 5 = 21071710800
Therefore, the lowest common multiple of 272,909,974,420,350 is 21071710800.
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.
272 x 909 x 974 x 420 x 350 = 35400474144000
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.
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
909 : 1, 3, 9, 101, 303, 909
974 : 1, 2, 487, 974
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
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 272,909,974,420,350, is 1.
Now, the common factors can be found like this.
272:2x 2x 2x 2x 17
909:3x 3x 101
974:2x 487
420:2x 2x 3x 5x 7
350:2x 5x 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 2x 3x 5x 7 = 1680
Therefore, the value for common factors is 1680.
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 = 35400474144000/(1x1680)
LCM = 35400474144000/1680
LCM = 21071710800
Thus, we can understand that the LCM of 272,909,974,420,350 is 21071710800.
