Given numbers are 401,640,805,692,527
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,640,805,692,527 is 3767098195840.
Find LCM of 401,640,805,692,527 with Prime Factorization
| 2 | 401, 640, 805, 692, 527 |
| 2 | 401, 320, 805, 346, 527 |
| 5 | 401, 160, 805, 173, 527 |
| 401, 32, 161, 173, 527 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 401 x 32 x 161 x 173 x 527 = 3767098195840
Therefore, the lowest common multiple of 401,640,805,692,527 is 3767098195840.
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.
401 x 640 x 805 x 692 x 527 = 75341963916800
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.
401 : 1, 401
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
805 : 1, 5, 7, 23, 35, 115, 161, 805
692 : 1, 2, 4, 173, 346, 692
527 : 1, 17, 31, 527
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,640,805,692,527, is 1.
Now, the common factors can be found like this.
401:401
640:2x 2x 2x 2x 2x 2x 2x 5
805:5x 7x 23
692:2x 2x 173
527:17x 31
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 5 = 20
Therefore, the value for common factors is 20.
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 = 75341963916800/(1x20)
LCM = 75341963916800/20
LCM = 3767098195840
Thus, we can understand that the LCM of 401,640,805,692,527 is 3767098195840.
