HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 381, 22237 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 381, 22237 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 381, 22237 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 381, 22237 is 1.
HCF(381, 22237) = 1
HCF of 381, 22237 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 381, 22237 is 1.
Highest Common Factor of 381,22237 is 1
Step 1: Since 22237 > 381, we apply the division lemma to 22237 and 381, to get
22237 = 381 x 58 + 139
Step 2: Since the reminder 381 ≠ 0, we apply division lemma to 139 and 381, to get
381 = 139 x 2 + 103
Step 3: We consider the new divisor 139 and the new remainder 103, and apply the division lemma to get
139 = 103 x 1 + 36
We consider the new divisor 103 and the new remainder 36,and apply the division lemma to get
103 = 36 x 2 + 31
We consider the new divisor 36 and the new remainder 31,and apply the division lemma to get
36 = 31 x 1 + 5
We consider the new divisor 31 and the new remainder 5,and apply the division lemma to get
31 = 5 x 6 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 381 and 22237 is 1
Notice that 1 = HCF(5,1) = HCF(31,5) = HCF(36,31) = HCF(103,36) = HCF(139,103) = HCF(381,139) = HCF(22237,381) .
