Given numbers are 537,780,992,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 537,780,992,221 is 588637920.
Find LCM of 537,780,992,221 with Prime Factorization
| 2 | 537, 780, 992, 221 |
| 2 | 537, 390, 496, 221 |
| 3 | 537, 195, 248, 221 |
| 13 | 179, 65, 248, 221 |
| 179, 5, 248, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 179 x 5 x 248 x 17 = 588637920
Therefore, the lowest common multiple of 537,780,992,221 is 588637920.
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.
537 x 780 x 992 x 221 = 91827515520
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.
537 : 1, 3, 179, 537
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 537,780,992,221, is 1.
Now, the common factors can be found like this.
537:3x 179
780:2x 2x 3x 5x 13
992:2x 2x 2x 2x 2x 31
221:13x 17
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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 91827515520/(1x156)
LCM = 91827515520/156
LCM = 588637920
Thus, we can understand that the LCM of 537,780,992,221 is 588637920.
