Given numbers are 721,777,532,377,406
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,777,532,377,406 is 2293048212.
Find LCM of 721,777,532,377,406 with Prime Factorization
| 2 | 721, 777, 532, 377, 406 |
| 7 | 721, 777, 266, 377, 203 |
| 29 | 103, 111, 38, 377, 29 |
| 103, 111, 38, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 29 x 103 x 111 x 38 x 13 x 1 = 2293048212
Therefore, the lowest common multiple of 721,777,532,377,406 is 2293048212.
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.
721 x 777 x 532 x 377 x 406 = 45617901129528
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.
721 : 1, 7, 103, 721
777 : 1, 3, 7, 21, 37, 111, 259, 777
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
377 : 1, 13, 29, 377
406 : 1, 2, 7, 14, 29, 58, 203, 406
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,777,532,377,406, is 1.
Now, the common factors can be found like this.
721:7x 103
777:3x 7x 37
532:2x 2x 7x 19
377:13x 29
406:2x 7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 7x 29 = 19894
Therefore, the value for common factors is 19894.
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 = 45617901129528/(1x19894)
LCM = 45617901129528/19894
LCM = 2293048212
Thus, we can understand that the LCM of 721,777,532,377,406 is 2293048212.
