Given numbers are 746,391,697,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 746,391,697,779 is 227223394.
Find LCM of 746,391,697,779 with Prime Factorization
| 17 | 746, 391, 697, 779 |
| 41 | 746, 23, 41, 779 |
| 746, 23, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
17 x 41 x 746 x 23 x 1 x 19 = 227223394
Therefore, the lowest common multiple of 746,391,697,779 is 227223394.
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 391 x 697 x 779 = 158374705618
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
391 : 1, 17, 23, 391
697 : 1, 17, 41, 697
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 746,391,697,779, is 1.
Now, the common factors can be found like this.
746:2x 373
391:17x 23
697:17x 41
779:19x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 41 = 697
Therefore, the value for common factors is 697.
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 = 158374705618/(1x697)
LCM = 158374705618/697
LCM = 227223394
Thus, we can understand that the LCM of 746,391,697,779 is 227223394.
