Given numbers are 361,661,779,517,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 361,661,779,517,420 is 2124380721540.
Find LCM of 361,661,779,517,420 with Prime Factorization
19 | 361, 661, 779, 517, 420 |
19, 661, 41, 517, 420 |
Multiply the prime numbers at the bottom and the left side.
19 x 19 x 661 x 41 x 517 x 420 = 2124380721540
Therefore, the lowest common multiple of 361,661,779,517,420 is 2124380721540.
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.
361 x 661 x 779 x 517 x 420 = 40363233709260
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.
361 : 1, 19, 361
661 : 1, 661
779 : 1, 19, 41, 779
517 : 1, 11, 47, 517
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,661,779,517,420, is 1.
Now, the common factors can be found like this.
361:19x 19
661:661
779:19x 41
517:11x 47
420:2x 2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 40363233709260/(1x19)
LCM = 40363233709260/19
LCM = 2124380721540
Thus, we can understand that the LCM of 361,661,779,517,420 is 2124380721540.
