HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 819, 712, 222 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 819, 712, 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 819, 712, 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 819, 712, 222 is 1.

HCF(819, 712, 222) = 1

Highest common factor (HCF) of 819, 712, 222 is 1.

Highest Common Factor of 819,712,222 using Euclid's algorithm

Highest Common Factor of 819,712,222 is 1

Step 1: Since 819 > 712, we apply the division lemma to 819 and 712, to get

819 = 712 x 1 + 107

Step 2: Since the reminder 712 ≠ 0, we apply division lemma to 107 and 712, to get

712 = 107 x 6 + 70

Step 3: We consider the new divisor 107 and the new remainder 70, and apply the division lemma to get

107 = 70 x 1 + 37

We consider the new divisor 70 and the new remainder 37,and apply the division lemma to get

70 = 37 x 1 + 33

We consider the new divisor 37 and the new remainder 33,and apply the division lemma to get

37 = 33 x 1 + 4

We consider the new divisor 33 and the new remainder 4,and apply the division lemma to get

33 = 4 x 8 + 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 819 and 712 is 1

Notice that 1 = HCF(4,1) = HCF(33,4) = HCF(37,33) = HCF(70,37) = HCF(107,70) = HCF(712,107) = HCF(819,712) .

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) .
