Given numbers are 369,588,556,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 369,588,556,646 is 3247130628.
Find LCM of 369,588,556,646 with Prime Factorization
2 | 369, 588, 556, 646 |
2 | 369, 294, 278, 323 |
3 | 369, 147, 139, 323 |
123, 49, 139, 323 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 123 x 49 x 139 x 323 = 3247130628
Therefore, the lowest common multiple of 369,588,556,646 is 3247130628.
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.
369 x 588 x 556 x 646 = 77931135072
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.
369 : 1, 3, 9, 41, 123, 369
588 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 49, 84, 98, 147, 196, 294, 588
556 : 1, 2, 4, 139, 278, 556
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 369,588,556,646, is 1.
Now, the common factors can be found like this.
369:3x 3x 41
588:2x 2x 3x 7x 7
556:2x 2x 139
646:2x 17x 19
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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 77931135072/(1x24)
LCM = 77931135072/24
LCM = 3247130628
Thus, we can understand that the LCM of 369,588,556,646 is 3247130628.
