HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2139, 9422 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 2139, 9422 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 2139, 9422 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 2139, 9422 is 1.
HCF(2139, 9422) = 1
HCF of 2139, 9422 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2139, 9422 is 1.
Highest Common Factor of 2139,9422 is 1
Step 1: Since 9422 > 2139, we apply the division lemma to 9422 and 2139, to get
9422 = 2139 x 4 + 866
Step 2: Since the reminder 2139 ≠ 0, we apply division lemma to 866 and 2139, to get
2139 = 866 x 2 + 407
Step 3: We consider the new divisor 866 and the new remainder 407, and apply the division lemma to get
866 = 407 x 2 + 52
We consider the new divisor 407 and the new remainder 52,and apply the division lemma to get
407 = 52 x 7 + 43
We consider the new divisor 52 and the new remainder 43,and apply the division lemma to get
52 = 43 x 1 + 9
We consider the new divisor 43 and the new remainder 9,and apply the division lemma to get
43 = 9 x 4 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 2139 and 9422 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(43,9) = HCF(52,43) = HCF(407,52) = HCF(866,407) = HCF(2139,866) = HCF(9422,2139) .
