Given numbers are 374,427,748,320,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 374,427,748,320,781 is 1814169280.
Find LCM of 374,427,748,320,781 with Prime Factorization
| 2 | 374, 427, 748, 320, 781 |
| 2 | 187, 427, 374, 160, 781 |
| 11 | 187, 427, 187, 80, 781 |
| 17 | 17, 427, 17, 80, 71 |
| 1, 427, 1, 80, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 17 x 1 x 427 x 1 x 80 x 71 = 1814169280
Therefore, the lowest common multiple of 374,427,748,320,781 is 1814169280.
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.
374 x 427 x 748 x 320 x 781 = 29853969671680
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.
374 : 1, 2, 11, 17, 22, 34, 187, 374
427 : 1, 7, 61, 427
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 374,427,748,320,781, is 1.
Now, the common factors can be found like this.
374:2x 11x 17
427:7x 61
748:2x 2x 11x 17
320:2x 2x 2x 2x 2x 2x 5
781:11x 71
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 2x 11x 11x 17 = 16456
Therefore, the value for common factors is 16456.
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 = 29853969671680/(1x16456)
LCM = 29853969671680/16456
LCM = 1814169280
Thus, we can understand that the LCM of 374,427,748,320,781 is 1814169280.
