Given numbers are 781,792,842,248
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,792,842,248 is 733883832.
Find LCM of 781,792,842,248 with Prime Factorization
2 | 781, 792, 842, 248 |
2 | 781, 396, 421, 124 |
2 | 781, 198, 421, 62 |
11 | 781, 99, 421, 31 |
71, 9, 421, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 71 x 9 x 421 x 31 = 733883832
Therefore, the lowest common multiple of 781,792,842,248 is 733883832.
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 792 x 842 x 248 = 129163554432
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
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
842 : 1, 2, 421, 842
248 : 1, 2, 4, 8, 31, 62, 124, 248
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,792,842,248, is 1.
Now, the common factors can be found like this.
781:11x 71
792:2x 2x 2x 3x 3x 11
842:2x 421
248:2x 2x 2x 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 2x 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 129163554432/(1x176)
LCM = 129163554432/176
LCM = 733883832
Thus, we can understand that the LCM of 781,792,842,248 is 733883832.
