Given numbers are 425,561,754,620,191
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 425,561,754,620,191 is 125227373700.
Find LCM of 425,561,754,620,191 with Prime Factorization
| 2 | 425, 561, 754, 620, 191 |
| 5 | 425, 561, 377, 310, 191 |
| 17 | 85, 561, 377, 62, 191 |
| 5, 33, 377, 62, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 5 x 33 x 377 x 62 x 191 = 125227373700
Therefore, the lowest common multiple of 425,561,754,620,191 is 125227373700.
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.
425 x 561 x 754 x 620 x 191 = 21288653529000
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.
425 : 1, 5, 17, 25, 85, 425
561 : 1, 3, 11, 17, 33, 51, 187, 561
754 : 1, 2, 13, 26, 29, 58, 377, 754
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
191 : 1, 191
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 425,561,754,620,191, is 1.
Now, the common factors can be found like this.
425:5x 5x 17
561:3x 11x 17
754:2x 13x 29
620:2x 2x 5x 31
191:191
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 17 = 170
Therefore, the value for common factors is 170.
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 = 21288653529000/(1x170)
LCM = 21288653529000/170
LCM = 125227373700
Thus, we can understand that the LCM of 425,561,754,620,191 is 125227373700.
