Given numbers are 771,821,893,851,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,821,893,851,247 is 6253482033669.
Find LCM of 771,821,893,851,247 with Prime Factorization
19 | 771, 821, 893, 851, 247 |
771, 821, 47, 851, 13 |
Multiply the prime numbers at the bottom and the left side.
19 x 771 x 821 x 47 x 851 x 13 = 6253482033669
Therefore, the lowest common multiple of 771,821,893,851,247 is 6253482033669.
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 821 x 893 x 851 x 247 = 118816158639711
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
821 : 1, 821
893 : 1, 19, 47, 893
851 : 1, 23, 37, 851
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,821,893,851,247, is 1.
Now, the common factors can be found like this.
771:3x 257
821:821
893:19x 47
851:23x 37
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 118816158639711/(1x19)
LCM = 118816158639711/19
LCM = 6253482033669
Thus, we can understand that the LCM of 771,821,893,851,247 is 6253482033669.
