HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 211, 998, 755 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 211, 998, 755 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 211, 998, 755 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 211, 998, 755 is 1.

HCF(211, 998, 755) = 1

Highest common factor (HCF) of 211, 998, 755 is 1.

Highest Common Factor of 211,998,755 using Euclid's algorithm

Highest Common Factor of 211,998,755 is 1

Step 1: Since 998 > 211, we apply the division lemma to 998 and 211, to get

998 = 211 x 4 + 154

Step 2: Since the reminder 211 ≠ 0, we apply division lemma to 154 and 211, to get

211 = 154 x 1 + 57

Step 3: We consider the new divisor 154 and the new remainder 57, and apply the division lemma to get

154 = 57 x 2 + 40

We consider the new divisor 57 and the new remainder 40,and apply the division lemma to get

57 = 40 x 1 + 17

We consider the new divisor 40 and the new remainder 17,and apply the division lemma to get

40 = 17 x 2 + 6

We consider the new divisor 17 and the new remainder 6,and apply the division lemma to get

17 = 6 x 2 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 211 and 998 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(17,6) = HCF(40,17) = HCF(57,40) = HCF(154,57) = HCF(211,154) = HCF(998,211) .

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

Step 1: Since 755 > 1, we apply the division lemma to 755 and 1, to get

755 = 1 x 755 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 755 is 1

Notice that 1 = HCF(755,1) .
