Given numbers are 760,238,903,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 760,238,903,420 is 11666760.
Find LCM of 760,238,903,420 with Prime Factorization
| 2 | 760, 238, 903, 420 |
| 2 | 380, 119, 903, 210 |
| 3 | 190, 119, 903, 105 |
| 5 | 190, 119, 301, 35 |
| 7 | 38, 119, 301, 7 |
| 38, 17, 43, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 38 x 17 x 43 x 1 = 11666760
Therefore, the lowest common multiple of 760,238,903,420 is 11666760.
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.
760 x 238 x 903 x 420 = 68600548800
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.
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
238 : 1, 2, 7, 14, 17, 34, 119, 238
903 : 1, 3, 7, 21, 43, 129, 301, 903
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 760,238,903,420, is 1.
Now, the common factors can be found like this.
760:2x 2x 2x 5x 19
238:2x 7x 17
903:3x 7x 43
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 2x 3x 5x 7x 7 = 5880
Therefore, the value for common factors is 5880.
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 = 68600548800/(1x5880)
LCM = 68600548800/5880
LCM = 11666760
Thus, we can understand that the LCM of 760,238,903,420 is 11666760.
