HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 793, 491, 222 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 793, 491, 222 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 793, 491, 222 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 793, 491, 222 is 1.

HCF(793, 491, 222) = 1

HCF of 793, 491, 222 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 793, 491, 222 is 1.

Highest Common Factor of 793,491,222 using Euclid's algorithm

Highest Common Factor of 793,491,222 is 1

Step 1: Since 793 > 491, we apply the division lemma to 793 and 491, to get

793 = 491 x 1 + 302

Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 302 and 491, to get

491 = 302 x 1 + 189

Step 3: We consider the new divisor 302 and the new remainder 189, and apply the division lemma to get

302 = 189 x 1 + 113

We consider the new divisor 189 and the new remainder 113,and apply the division lemma to get

189 = 113 x 1 + 76

We consider the new divisor 113 and the new remainder 76,and apply the division lemma to get

113 = 76 x 1 + 37

We consider the new divisor 76 and the new remainder 37,and apply the division lemma to get

76 = 37 x 2 + 2

We consider the new divisor 37 and the new remainder 2,and apply the division lemma to get

37 = 2 x 18 + 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 793 and 491 is 1

Notice that 1 = HCF(2,1) = HCF(37,2) = HCF(76,37) = HCF(113,76) = HCF(189,113) = HCF(302,189) = HCF(491,302) = HCF(793,491) .

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

Step 1: Since 222 > 1, we apply the division lemma to 222 and 1, to get

222 = 1 x 222 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 222 is 1

Notice that 1 = HCF(222,1) .
