HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 857, 551, 871 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 857, 551, 871 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 857, 551, 871 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 857, 551, 871 is 1.
HCF(857, 551, 871) = 1
HCF of 857, 551, 871 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 857, 551, 871 is 1.
Highest Common Factor of 857,551,871 is 1
Step 1: Since 857 > 551, we apply the division lemma to 857 and 551, to get
857 = 551 x 1 + 306
Step 2: Since the reminder 551 ≠ 0, we apply division lemma to 306 and 551, to get
551 = 306 x 1 + 245
Step 3: We consider the new divisor 306 and the new remainder 245, and apply the division lemma to get
306 = 245 x 1 + 61
We consider the new divisor 245 and the new remainder 61,and apply the division lemma to get
245 = 61 x 4 + 1
We consider the new divisor 61 and the new remainder 1,and apply the division lemma to get
61 = 1 x 61 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 857 and 551 is 1
Notice that 1 = HCF(61,1) = HCF(245,61) = HCF(306,245) = HCF(551,306) = HCF(857,551) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 871 > 1, we apply the division lemma to 871 and 1, to get
871 = 1 x 871 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 871 is 1
Notice that 1 = HCF(871,1) .
