Given numbers are 771,542,308,278,847
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,542,308,278,847 is 98397003012.
Find LCM of 771,542,308,278,847 with Prime Factorization
| 2 | 771, 542, 308, 278, 847 |
| 7 | 771, 271, 154, 139, 847 |
| 11 | 771, 271, 22, 139, 121 |
| 771, 271, 2, 139, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 771 x 271 x 2 x 139 x 11 = 98397003012
Therefore, the lowest common multiple of 771,542,308,278,847 is 98397003012.
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.
771 x 542 x 308 x 278 x 847 = 30306276927696
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.
771 : 1, 3, 257, 771
542 : 1, 2, 271, 542
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
278 : 1, 2, 139, 278
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,542,308,278,847, is 1.
Now, the common factors can be found like this.
771:3x 257
542:2x 271
308:2x 2x 7x 11
278:2x 139
847:7x 11x 11
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 7x 11 = 308
Therefore, the value for common factors is 308.
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 = 30306276927696/(1x308)
LCM = 30306276927696/308
LCM = 98397003012
Thus, we can understand that the LCM of 771,542,308,278,847 is 98397003012.
