Given numbers are 422,740,291,436
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 422,740,291,436 is 4952604660.
Find LCM of 422,740,291,436 with Prime Factorization
| 2 | 422, 740, 291, 436 |
| 2 | 211, 370, 291, 218 |
| 211, 185, 291, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 211 x 185 x 291 x 109 = 4952604660
Therefore, the lowest common multiple of 422,740,291,436 is 4952604660.
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.
422 x 740 x 291 x 436 = 39620837280
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.
422 : 1, 2, 211, 422
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
291 : 1, 3, 97, 291
436 : 1, 2, 4, 109, 218, 436
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,740,291,436, is 1.
Now, the common factors can be found like this.
422:2x 211
740:2x 2x 5x 37
291:3x 97
436:2x 2x 109
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 2 = 8
Therefore, the value for common factors is 8.
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 = 39620837280/(1x8)
LCM = 39620837280/8
LCM = 4952604660
Thus, we can understand that the LCM of 422,740,291,436 is 4952604660.
