HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 187, 311 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 187, 311 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 187, 311 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 187, 311 is 1.
HCF(187, 311) = 1
HCF of 187, 311 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 187, 311 is 1.
Highest Common Factor of 187,311 is 1
Step 1: Since 311 > 187, we apply the division lemma to 311 and 187, to get
311 = 187 x 1 + 124
Step 2: Since the reminder 187 ≠ 0, we apply division lemma to 124 and 187, to get
187 = 124 x 1 + 63
Step 3: We consider the new divisor 124 and the new remainder 63, and apply the division lemma to get
124 = 63 x 1 + 61
We consider the new divisor 63 and the new remainder 61,and apply the division lemma to get
63 = 61 x 1 + 2
We consider the new divisor 61 and the new remainder 2,and apply the division lemma to get
61 = 2 x 30 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 187 and 311 is 1
Notice that 1 = HCF(2,1) = HCF(61,2) = HCF(63,61) = HCF(124,63) = HCF(187,124) = HCF(311,187) .
