Given numbers are 382,618,721,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 382,618,721,689 is 569297274.
Find LCM of 382,618,721,689 with Prime Factorization
2 | 382, 618, 721, 689 |
103 | 191, 309, 721, 689 |
191, 3, 7, 689 |
Multiply the prime numbers at the bottom and the left side.
2 x 103 x 191 x 3 x 7 x 689 = 569297274
Therefore, the lowest common multiple of 382,618,721,689 is 569297274.
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.
382 x 618 x 721 x 689 = 117275238444
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.
382 : 1, 2, 191, 382
618 : 1, 2, 3, 6, 103, 206, 309, 618
721 : 1, 7, 103, 721
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 382,618,721,689, is 1.
Now, the common factors can be found like this.
382:2x 191
618:2x 3x 103
721:7x 103
689:13x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 103 = 206
Therefore, the value for common factors is 206.
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 = 117275238444/(1x206)
LCM = 117275238444/206
LCM = 569297274
Thus, we can understand that the LCM of 382,618,721,689 is 569297274.
