Given numbers are 371,563,143,721,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 371,563,143,721,420 is 184589425020.
Find LCM of 371,563,143,721,420 with Prime Factorization
| 7 | 371, 563, 143, 721, 420 |
| 53, 563, 143, 103, 60 |
Multiply the prime numbers at the bottom and the left side.
7 x 53 x 563 x 143 x 103 x 60 = 184589425020
Therefore, the lowest common multiple of 371,563,143,721,420 is 184589425020.
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.
371 x 563 x 143 x 721 x 420 = 9044881825980
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.
371 : 1, 7, 53, 371
563 : 1, 563
143 : 1, 11, 13, 143
721 : 1, 7, 103, 721
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 371,563,143,721,420, is 1.
Now, the common factors can be found like this.
371:7x 53
563:563
143:11x 13
721:7x 103
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.
7x 7 = 49
Therefore, the value for common factors is 49.
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 = 9044881825980/(1x49)
LCM = 9044881825980/49
LCM = 184589425020
Thus, we can understand that the LCM of 371,563,143,721,420 is 184589425020.
