HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 791, 80 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 791, 80 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 791, 80 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 791, 80 is 1.
HCF(791, 80) = 1
HCF of 791, 80 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 791, 80 is 1.
Highest Common Factor of 791,80 is 1
Step 1: Since 791 > 80, we apply the division lemma to 791 and 80, to get
791 = 80 x 9 + 71
Step 2: Since the reminder 80 ≠ 0, we apply division lemma to 71 and 80, to get
80 = 71 x 1 + 9
Step 3: We consider the new divisor 71 and the new remainder 9, and apply the division lemma to get
71 = 9 x 7 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 791 and 80 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(71,9) = HCF(80,71) = HCF(791,80) .
