HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 189, 9558 i.e. 27 the largest integer that leaves a remainder zero for all numbers.
HCF of 189, 9558 is 27 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 189, 9558 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 189, 9558 is 27.
HCF(189, 9558) = 27
HCF of 189, 9558 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 189, 9558 is 27.
Highest Common Factor of 189,9558 is 27
Step 1: Since 9558 > 189, we apply the division lemma to 9558 and 189, to get
9558 = 189 x 50 + 108
Step 2: Since the reminder 189 ≠ 0, we apply division lemma to 108 and 189, to get
189 = 108 x 1 + 81
Step 3: We consider the new divisor 108 and the new remainder 81, and apply the division lemma to get
108 = 81 x 1 + 27
We consider the new divisor 81 and the new remainder 27, and apply the division lemma to get
81 = 27 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 189 and 9558 is 27
Notice that 27 = HCF(81,27) = HCF(108,81) = HCF(189,108) = HCF(9558,189) .
