HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 863, 1913, 3777 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 863, 1913, 3777 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 863, 1913, 3777 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 863, 1913, 3777 is 1.
HCF(863, 1913, 3777) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 863, 1913, 3777 is 1.
Step 1: Since 1913 > 863, we apply the division lemma to 1913 and 863, to get
1913 = 863 x 2 + 187
Step 2: Since the reminder 863 ≠ 0, we apply division lemma to 187 and 863, to get
863 = 187 x 4 + 115
Step 3: We consider the new divisor 187 and the new remainder 115, and apply the division lemma to get
187 = 115 x 1 + 72
We consider the new divisor 115 and the new remainder 72,and apply the division lemma to get
115 = 72 x 1 + 43
We consider the new divisor 72 and the new remainder 43,and apply the division lemma to get
72 = 43 x 1 + 29
We consider the new divisor 43 and the new remainder 29,and apply the division lemma to get
43 = 29 x 1 + 14
We consider the new divisor 29 and the new remainder 14,and apply the division lemma to get
29 = 14 x 2 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 863 and 1913 is 1
Notice that 1 = HCF(14,1) = HCF(29,14) = HCF(43,29) = HCF(72,43) = HCF(115,72) = HCF(187,115) = HCF(863,187) = HCF(1913,863) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 3777 > 1, we apply the division lemma to 3777 and 1, to get
3777 = 1 x 3777 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 3777 is 1
Notice that 1 = HCF(3777,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
