Given numbers are 746,377,769,261,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 746,377,769,261,420 is 136253311740.
Find LCM of 746,377,769,261,420 with Prime Factorization
| 2 | 746, 377, 769, 261, 420 |
| 3 | 373, 377, 769, 261, 210 |
| 29 | 373, 377, 769, 87, 70 |
| 373, 13, 769, 3, 70 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 373 x 13 x 769 x 3 x 70 = 136253311740
Therefore, the lowest common multiple of 746,377,769,261,420 is 136253311740.
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.
746 x 377 x 769 x 261 x 420 = 23708076242760
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.
746 : 1, 2, 373, 746
377 : 1, 13, 29, 377
769 : 1, 769
261 : 1, 3, 9, 29, 87, 261
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 746,377,769,261,420, is 1.
Now, the common factors can be found like this.
746:2x 373
377:13x 29
769:769
261:3x 3x 29
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 3x 29 = 174
Therefore, the value for common factors is 174.
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 = 23708076242760/(1x174)
LCM = 23708076242760/174
LCM = 136253311740
Thus, we can understand that the LCM of 746,377,769,261,420 is 136253311740.
