HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 212, 726, 189 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 212, 726, 189 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 212, 726, 189 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 212, 726, 189 is 1.

HCF(212, 726, 189) = 1

Highest common factor (HCF) of 212, 726, 189 is 1.

Highest Common Factor of 212,726,189 using Euclid's algorithm

Highest Common Factor of 212,726,189 is 1

Step 1: Since 726 > 212, we apply the division lemma to 726 and 212, to get

726 = 212 x 3 + 90

Step 2: Since the reminder 212 ≠ 0, we apply division lemma to 90 and 212, to get

212 = 90 x 2 + 32

Step 3: We consider the new divisor 90 and the new remainder 32, and apply the division lemma to get

90 = 32 x 2 + 26

We consider the new divisor 32 and the new remainder 26,and apply the division lemma to get

32 = 26 x 1 + 6

We consider the new divisor 26 and the new remainder 6,and apply the division lemma to get

26 = 6 x 4 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 212 and 726 is 2

Notice that 2 = HCF(6,2) = HCF(26,6) = HCF(32,26) = HCF(90,32) = HCF(212,90) = HCF(726,212) .

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

Step 1: Since 189 > 2, we apply the division lemma to 189 and 2, to get

189 = 2 x 94 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 189 is 1

Notice that 1 = HCF(2,1) = HCF(189,2) .
