Given numbers are 985,817,674,551
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 985,817,674,551 is 15729545770.
Find LCM of 985,817,674,551 with Prime Factorization
19 | 985, 817, 674, 551 |
985, 43, 674, 29 |
Multiply the prime numbers at the bottom and the left side.
19 x 985 x 43 x 674 x 29 = 15729545770
Therefore, the lowest common multiple of 985,817,674,551 is 15729545770.
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.
985 x 817 x 674 x 551 = 298861369630
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.
985 : 1, 5, 197, 985
817 : 1, 19, 43, 817
674 : 1, 2, 337, 674
551 : 1, 19, 29, 551
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,817,674,551, is 1.
Now, the common factors can be found like this.
985:5x 197
817:19x 43
674:2x 337
551:19x 29
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 = 298861369630/(1x19)
LCM = 298861369630/19
LCM = 15729545770
Thus, we can understand that the LCM of 985,817,674,551 is 15729545770.
