Given numbers are 174,421,842,203
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 174,421,842,203 is 512778.
Find LCM of 174,421,842,203 with Prime Factorization
| 2 | 174, 421, 842, 203 |
| 29 | 87, 421, 421, 203 |
| 421 | 3, 421, 421, 7 |
| 3, 1, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 29 x 421 x 3 x 1 x 1 x 7 = 512778
Therefore, the lowest common multiple of 174,421,842,203 is 512778.
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.
174 x 421 x 842 x 203 = 12521013204
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.
174 : 1, 2, 3, 6, 29, 58, 87, 174
421 : 1, 421
842 : 1, 2, 421, 842
203 : 1, 7, 29, 203
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 174,421,842,203, is 1.
Now, the common factors can be found like this.
174:2x 3x 29
421:421
842:2x 421
203:7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 29x 421 = 24418
Therefore, the value for common factors is 24418.
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 = 12521013204/(1x24418)
LCM = 12521013204/24418
LCM = 512778
Thus, we can understand that the LCM of 174,421,842,203 is 512778.
