Given numbers are 721,779,171,836
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,779,171,836 is 222416964.
Find LCM of 721,779,171,836 with Prime Factorization
19 | 721, 779, 171, 836 |
721, 41, 9, 44 |
Multiply the prime numbers at the bottom and the left side.
19 x 721 x 41 x 9 x 44 = 222416964
Therefore, the lowest common multiple of 721,779,171,836 is 222416964.
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 779 x 171 x 836 = 80292524004
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
779 : 1, 19, 41, 779
171 : 1, 3, 9, 19, 57, 171
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,779,171,836, is 1.
Now, the common factors can be found like this.
721:7x 103
779:19x 41
171:3x 3x 19
836:2x 2x 11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 19 = 361
Therefore, the value for common factors is 361.
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 = 80292524004/(1x361)
LCM = 80292524004/361
LCM = 222416964
Thus, we can understand that the LCM of 721,779,171,836 is 222416964.
