Given numbers are 781,926,649,748,269
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,926,649,748,269 is 390252082484.
Find LCM of 781,926,649,748,269 with Prime Factorization
| 2 | 781, 926, 649, 748, 269 |
| 11 | 781, 463, 649, 374, 269 |
| 71, 463, 59, 34, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 71 x 463 x 59 x 34 x 269 = 390252082484
Therefore, the lowest common multiple of 781,926,649,748,269 is 390252082484.
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.
781 x 926 x 649 x 748 x 269 = 94441003961128
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.
781 : 1, 11, 71, 781
926 : 1, 2, 463, 926
649 : 1, 11, 59, 649
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
269 : 1, 269
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,926,649,748,269, is 1.
Now, the common factors can be found like this.
781:11x 71
926:2x 463
649:11x 59
748:2x 2x 11x 17
269:269
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11 = 242
Therefore, the value for common factors is 242.
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 = 94441003961128/(1x242)
LCM = 94441003961128/242
LCM = 390252082484
Thus, we can understand that the LCM of 781,926,649,748,269 is 390252082484.
