HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 773, 969, 221 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 773, 969, 221 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 773, 969, 221 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 773, 969, 221 is 1.

HCF(773, 969, 221) = 1

HCF of 773, 969, 221 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 773, 969, 221 is 1.

Highest Common Factor of 773,969,221 using Euclid's algorithm

Highest Common Factor of 773,969,221 is 1

Step 1: Since 969 > 773, we apply the division lemma to 969 and 773, to get

969 = 773 x 1 + 196

Step 2: Since the reminder 773 ≠ 0, we apply division lemma to 196 and 773, to get

773 = 196 x 3 + 185

Step 3: We consider the new divisor 196 and the new remainder 185, and apply the division lemma to get

196 = 185 x 1 + 11

We consider the new divisor 185 and the new remainder 11,and apply the division lemma to get

185 = 11 x 16 + 9

We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get

11 = 9 x 1 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 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 773 and 969 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(185,11) = HCF(196,185) = HCF(773,196) = HCF(969,773) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 221 > 1, we apply the division lemma to 221 and 1, to get

221 = 1 x 221 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 221 is 1

Notice that 1 = HCF(221,1) .
