HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 387, 2117 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 387, 2117 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 387, 2117 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 387, 2117 is 1.
HCF(387, 2117) = 1
HCF of 387, 2117 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 387, 2117 is 1.
Highest Common Factor of 387,2117 is 1
Step 1: Since 2117 > 387, we apply the division lemma to 2117 and 387, to get
2117 = 387 x 5 + 182
Step 2: Since the reminder 387 ≠ 0, we apply division lemma to 182 and 387, to get
387 = 182 x 2 + 23
Step 3: We consider the new divisor 182 and the new remainder 23, and apply the division lemma to get
182 = 23 x 7 + 21
We consider the new divisor 23 and the new remainder 21,and apply the division lemma to get
23 = 21 x 1 + 2
We consider the new divisor 21 and the new remainder 2,and apply the division lemma to get
21 = 2 x 10 + 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 387 and 2117 is 1
Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(23,21) = HCF(182,23) = HCF(387,182) = HCF(2117,387) .
