HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 851, 189 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 851, 189 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 851, 189 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 851, 189 is 1.
HCF(851, 189) = 1
HCF of 851, 189 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 851, 189 is 1.
Highest Common Factor of 851,189 is 1
Step 1: Since 851 > 189, we apply the division lemma to 851 and 189, to get
851 = 189 x 4 + 95
Step 2: Since the reminder 189 ≠ 0, we apply division lemma to 95 and 189, to get
189 = 95 x 1 + 94
Step 3: We consider the new divisor 95 and the new remainder 94, and apply the division lemma to get
95 = 94 x 1 + 1
We consider the new divisor 94 and the new remainder 1, and apply the division lemma to get
94 = 1 x 94 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 851 and 189 is 1
Notice that 1 = HCF(94,1) = HCF(95,94) = HCF(189,95) = HCF(851,189) .
