Given numbers are 419,693,614,742,778
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 419,693,614,742,778 is 3675708813546.
Find LCM of 419,693,614,742,778 with Prime Factorization
| 2 | 419, 693, 614, 742, 778 |
| 7 | 419, 693, 307, 371, 389 |
| 419, 99, 307, 53, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 419 x 99 x 307 x 53 x 389 = 3675708813546
Therefore, the lowest common multiple of 419,693,614,742,778 is 3675708813546.
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.
419 x 693 x 614 x 742 x 778 = 102919846779288
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.
419 : 1, 419
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
614 : 1, 2, 307, 614
742 : 1, 2, 7, 14, 53, 106, 371, 742
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 419,693,614,742,778, is 1.
Now, the common factors can be found like this.
419:419
693:3x 3x 7x 11
614:2x 307
742:2x 7x 53
778:2x 389
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 7 = 28
Therefore, the value for common factors is 28.
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 = 102919846779288/(1x28)
LCM = 102919846779288/28
LCM = 3675708813546
Thus, we can understand that the LCM of 419,693,614,742,778 is 3675708813546.
