HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 658, 185, 211 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 658, 185, 211 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 658, 185, 211 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 658, 185, 211 is 1.

HCF(658, 185, 211) = 1

HCF of 658, 185, 211 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 658, 185, 211 is 1.

Highest Common Factor of 658,185,211 using Euclid's algorithm

Highest Common Factor of 658,185,211 is 1

Step 1: Since 658 > 185, we apply the division lemma to 658 and 185, to get

658 = 185 x 3 + 103

Step 2: Since the reminder 185 ≠ 0, we apply division lemma to 103 and 185, to get

185 = 103 x 1 + 82

Step 3: We consider the new divisor 103 and the new remainder 82, and apply the division lemma to get

103 = 82 x 1 + 21

We consider the new divisor 82 and the new remainder 21,and apply the division lemma to get

82 = 21 x 3 + 19

We consider the new divisor 21 and the new remainder 19,and apply the division lemma to get

21 = 19 x 1 + 2

We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get

19 = 2 x 9 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 658 and 185 is 1

Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(82,21) = HCF(103,82) = HCF(185,103) = HCF(658,185) .

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

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

211 = 1 x 211 + 0

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

Notice that 1 = HCF(211,1) .
