Given numbers are 693,187,779,510
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 693,187,779,510 is 91773990.
Find LCM of 693,187,779,510 with Prime Factorization
| 3 | 693, 187, 779, 510 |
| 11 | 231, 187, 779, 170 |
| 17 | 21, 17, 779, 170 |
| 21, 1, 779, 10 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 17 x 21 x 1 x 779 x 10 = 91773990
Therefore, the lowest common multiple of 693,187,779,510 is 91773990.
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.
693 x 187 x 779 x 510 = 51485208390
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.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
187 : 1, 11, 17, 187
779 : 1, 19, 41, 779
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,187,779,510, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
187:11x 17
779:19x 41
510:2x 3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 17 = 561
Therefore, the value for common factors is 561.
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 = 51485208390/(1x561)
LCM = 51485208390/561
LCM = 91773990
Thus, we can understand that the LCM of 693,187,779,510 is 91773990.
