HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 985, 819 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 985, 819 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 985, 819 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 985, 819 is 1.
HCF(985, 819) = 1
HCF of 985, 819 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 985, 819 is 1.
Highest Common Factor of 985,819 is 1
Step 1: Since 985 > 819, we apply the division lemma to 985 and 819, to get
985 = 819 x 1 + 166
Step 2: Since the reminder 819 ≠ 0, we apply division lemma to 166 and 819, to get
819 = 166 x 4 + 155
Step 3: We consider the new divisor 166 and the new remainder 155, and apply the division lemma to get
166 = 155 x 1 + 11
We consider the new divisor 155 and the new remainder 11,and apply the division lemma to get
155 = 11 x 14 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 985 and 819 is 1
Notice that 1 = HCF(11,1) = HCF(155,11) = HCF(166,155) = HCF(819,166) = HCF(985,819) .
