HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 93, 31, 79 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 93, 31, 79 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 93, 31, 79 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 93, 31, 79 is 1.
HCF(93, 31, 79) = 1
HCF of 93, 31, 79 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 93, 31, 79 is 1.
Highest Common Factor of 93,31,79 is 1
Step 1: Since 93 > 31, we apply the division lemma to 93 and 31, to get
93 = 31 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 31, the HCF of 93 and 31 is 31
Notice that 31 = HCF(93,31) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 79 > 31, we apply the division lemma to 79 and 31, to get
79 = 31 x 2 + 17
Step 2: Since the reminder 31 ≠ 0, we apply division lemma to 17 and 31, to get
31 = 17 x 1 + 14
Step 3: We consider the new divisor 17 and the new remainder 14, and apply the division lemma to get
17 = 14 x 1 + 3
We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get
14 = 3 x 4 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 31 and 79 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(17,14) = HCF(31,17) = HCF(79,31) .
