HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 720, 194, 196 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 720, 194, 196 is 2 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 720, 194, 196 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 720, 194, 196 is 2.
HCF(720, 194, 196) = 2
HCF of 720, 194, 196 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 720, 194, 196 is 2.
Highest Common Factor of 720,194,196 is 2
Step 1: Since 720 > 194, we apply the division lemma to 720 and 194, to get
720 = 194 x 3 + 138
Step 2: Since the reminder 194 ≠ 0, we apply division lemma to 138 and 194, to get
194 = 138 x 1 + 56
Step 3: We consider the new divisor 138 and the new remainder 56, and apply the division lemma to get
138 = 56 x 2 + 26
We consider the new divisor 56 and the new remainder 26,and apply the division lemma to get
56 = 26 x 2 + 4
We consider the new divisor 26 and the new remainder 4,and apply the division lemma to get
26 = 4 x 6 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 720 and 194 is 2
Notice that 2 = HCF(4,2) = HCF(26,4) = HCF(56,26) = HCF(138,56) = HCF(194,138) = HCF(720,194) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 196 > 2, we apply the division lemma to 196 and 2, to get
196 = 2 x 98 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 196 is 2
Notice that 2 = HCF(196,2) .
