HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 792, 205 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 792, 205 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 792, 205 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 792, 205 is 1.
HCF(792, 205) = 1
HCF of 792, 205 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 792, 205 is 1.
Highest Common Factor of 792,205 is 1
Step 1: Since 792 > 205, we apply the division lemma to 792 and 205, to get
792 = 205 x 3 + 177
Step 2: Since the reminder 205 ≠ 0, we apply division lemma to 177 and 205, to get
205 = 177 x 1 + 28
Step 3: We consider the new divisor 177 and the new remainder 28, and apply the division lemma to get
177 = 28 x 6 + 9
We consider the new divisor 28 and the new remainder 9,and apply the division lemma to get
28 = 9 x 3 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 792 and 205 is 1
Notice that 1 = HCF(9,1) = HCF(28,9) = HCF(177,28) = HCF(205,177) = HCF(792,205) .
