HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 993, 1285 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 993, 1285 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 993, 1285 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 993, 1285 is 1.
HCF(993, 1285) = 1
HCF of 993, 1285 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 993, 1285 is 1.
Highest Common Factor of 993,1285 is 1
Step 1: Since 1285 > 993, we apply the division lemma to 1285 and 993, to get
1285 = 993 x 1 + 292
Step 2: Since the reminder 993 ≠ 0, we apply division lemma to 292 and 993, to get
993 = 292 x 3 + 117
Step 3: We consider the new divisor 292 and the new remainder 117, and apply the division lemma to get
292 = 117 x 2 + 58
We consider the new divisor 117 and the new remainder 58,and apply the division lemma to get
117 = 58 x 2 + 1
We consider the new divisor 58 and the new remainder 1,and apply the division lemma to get
58 = 1 x 58 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 993 and 1285 is 1
Notice that 1 = HCF(58,1) = HCF(117,58) = HCF(292,117) = HCF(993,292) = HCF(1285,993) .
