HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 223, 813, 656 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 223, 813, 656 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 223, 813, 656 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 223, 813, 656 is 1.

HCF(223, 813, 656) = 1

Highest common factor (HCF) of 223, 813, 656 is 1.

Highest Common Factor of 223,813,656 using Euclid's algorithm

Highest Common Factor of 223,813,656 is 1

Step 1: Since 813 > 223, we apply the division lemma to 813 and 223, to get

813 = 223 x 3 + 144

Step 2: Since the reminder 223 ≠ 0, we apply division lemma to 144 and 223, to get

223 = 144 x 1 + 79

Step 3: We consider the new divisor 144 and the new remainder 79, and apply the division lemma to get

144 = 79 x 1 + 65

We consider the new divisor 79 and the new remainder 65,and apply the division lemma to get

79 = 65 x 1 + 14

We consider the new divisor 65 and the new remainder 14,and apply the division lemma to get

65 = 14 x 4 + 9

We consider the new divisor 14 and the new remainder 9,and apply the division lemma to get

14 = 9 x 1 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 223 and 813 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(14,9) = HCF(65,14) = HCF(79,65) = HCF(144,79) = HCF(223,144) = HCF(813,223) .

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

Step 1: Since 656 > 1, we apply the division lemma to 656 and 1, to get

656 = 1 x 656 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 656 is 1

Notice that 1 = HCF(656,1) .
