Given numbers are 161,120,454,361,491
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 161,120,454,361,491 is 777359075640.
Find LCM of 161,120,454,361,491 with Prime Factorization
2 | 161, 120, 454, 361, 491 |
161, 60, 227, 361, 491 |
Multiply the prime numbers at the bottom and the left side.
2 x 161 x 60 x 227 x 361 x 491 = 777359075640
Therefore, the lowest common multiple of 161,120,454,361,491 is 777359075640.
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.
161 x 120 x 454 x 361 x 491 = 1554718151280
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.
161 : 1, 7, 23, 161
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
454 : 1, 2, 227, 454
361 : 1, 19, 361
491 : 1, 491
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,120,454,361,491, is 1.
Now, the common factors can be found like this.
161:7x 23
120:2x 2x 2x 3x 5
454:2x 227
361:19x 19
491:491
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 1554718151280/(1x2)
LCM = 1554718151280/2
LCM = 777359075640
Thus, we can understand that the LCM of 161,120,454,361,491 is 777359075640.
