HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 217, 822, 783 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 217, 822, 783 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 217, 822, 783 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 217, 822, 783 is 1.

HCF(217, 822, 783) = 1

Highest common factor (HCF) of 217, 822, 783 is 1.

Highest Common Factor of 217,822,783 using Euclid's algorithm

Highest Common Factor of 217,822,783 is 1

Step 1: Since 822 > 217, we apply the division lemma to 822 and 217, to get

822 = 217 x 3 + 171

Step 2: Since the reminder 217 ≠ 0, we apply division lemma to 171 and 217, to get

217 = 171 x 1 + 46

Step 3: We consider the new divisor 171 and the new remainder 46, and apply the division lemma to get

171 = 46 x 3 + 33

We consider the new divisor 46 and the new remainder 33,and apply the division lemma to get

46 = 33 x 1 + 13

We consider the new divisor 33 and the new remainder 13,and apply the division lemma to get

33 = 13 x 2 + 7

We consider the new divisor 13 and the new remainder 7,and apply the division lemma to get

13 = 7 x 1 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 217 and 822 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(33,13) = HCF(46,33) = HCF(171,46) = HCF(217,171) = HCF(822,217) .

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

Step 1: Since 783 > 1, we apply the division lemma to 783 and 1, to get

783 = 1 x 783 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 783 is 1

Notice that 1 = HCF(783,1) .
