HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 774, 643, 796 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 774, 643, 796 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 774, 643, 796 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 774, 643, 796 is 1.
HCF(774, 643, 796) = 1
HCF of 774, 643, 796 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 774, 643, 796 is 1.
Highest Common Factor of 774,643,796 is 1
Step 1: Since 774 > 643, we apply the division lemma to 774 and 643, to get
774 = 643 x 1 + 131
Step 2: Since the reminder 643 ≠ 0, we apply division lemma to 131 and 643, to get
643 = 131 x 4 + 119
Step 3: We consider the new divisor 131 and the new remainder 119, and apply the division lemma to get
131 = 119 x 1 + 12
We consider the new divisor 119 and the new remainder 12,and apply the division lemma to get
119 = 12 x 9 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 774 and 643 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(119,12) = HCF(131,119) = HCF(643,131) = HCF(774,643) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 796 > 1, we apply the division lemma to 796 and 1, to get
796 = 1 x 796 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 796 is 1
Notice that 1 = HCF(796,1) .
