HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 412, 774, 197 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 412, 774, 197 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 412, 774, 197 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 412, 774, 197 is 1.
HCF(412, 774, 197) = 1
HCF of 412, 774, 197 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 412, 774, 197 is 1.
Highest Common Factor of 412,774,197 is 1
Step 1: Since 774 > 412, we apply the division lemma to 774 and 412, to get
774 = 412 x 1 + 362
Step 2: Since the reminder 412 ≠ 0, we apply division lemma to 362 and 412, to get
412 = 362 x 1 + 50
Step 3: We consider the new divisor 362 and the new remainder 50, and apply the division lemma to get
362 = 50 x 7 + 12
We consider the new divisor 50 and the new remainder 12,and apply the division lemma to get
50 = 12 x 4 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 412 and 774 is 2
Notice that 2 = HCF(12,2) = HCF(50,12) = HCF(362,50) = HCF(412,362) = HCF(774,412) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 197 > 2, we apply the division lemma to 197 and 2, to get
197 = 2 x 98 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 197 is 1
Notice that 1 = HCF(2,1) = HCF(197,2) .
