Given numbers are 194,438,669,380,312
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 194,438,669,380,312 is 46803427320.
Find LCM of 194,438,669,380,312 with Prime Factorization
| 2 | 194, 438, 669, 380, 312 |
| 2 | 97, 219, 669, 190, 156 |
| 3 | 97, 219, 669, 95, 78 |
| 97, 73, 223, 95, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 97 x 73 x 223 x 95 x 26 = 46803427320
Therefore, the lowest common multiple of 194,438,669,380,312 is 46803427320.
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.
194 x 438 x 669 x 380 x 312 = 6739693534080
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.
194 : 1, 2, 97, 194
438 : 1, 2, 3, 6, 73, 146, 219, 438
669 : 1, 3, 223, 669
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 194,438,669,380,312, is 1.
Now, the common factors can be found like this.
194:2x 97
438:2x 3x 73
669:3x 223
380:2x 2x 5x 19
312:2x 2x 2x 3x 13
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 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 6739693534080/(1x144)
LCM = 6739693534080/144
LCM = 46803427320
Thus, we can understand that the LCM of 194,438,669,380,312 is 46803427320.
