Given numbers are 387,172,989,419,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 387,172,989,419,620 is 2312301780.
Find LCM of 387,172,989,419,620 with Prime Factorization
2 | 387, 172, 989, 419, 620 |
2 | 387, 86, 989, 419, 310 |
43 | 387, 43, 989, 419, 155 |
9, 1, 23, 419, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 9 x 1 x 23 x 419 x 155 = 2312301780
Therefore, the lowest common multiple of 387,172,989,419,620 is 2312301780.
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.
387 x 172 x 989 x 419 x 620 = 17101783964880
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.
387 : 1, 3, 9, 43, 129, 387
172 : 1, 2, 4, 43, 86, 172
989 : 1, 23, 43, 989
419 : 1, 419
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,172,989,419,620, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
172:2x 2x 43
989:23x 43
419:419
620:2x 2x 5x 31
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 43x 43 = 7396
Therefore, the value for common factors is 7396.
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 = 17101783964880/(1x7396)
LCM = 17101783964880/7396
LCM = 2312301780
Thus, we can understand that the LCM of 387,172,989,419,620 is 2312301780.
