HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 217, 330, 658, 331 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 217, 330, 658, 331 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, 330, 658, 331 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, 330, 658, 331 is 1.

HCF(217, 330, 658, 331) = 1

Highest Common Factor of 217,330,658,331 using Euclid's algorithm

Highest Common Factor of 217,330,658,331 is 1

Step 1: Since 330 > 217, we apply the division lemma to 330 and 217, to get

330 = 217 x 1 + 113

Step 2: Since the reminder 217 ≠ 0, we apply division lemma to 113 and 217, to get

217 = 113 x 1 + 104

Step 3: We consider the new divisor 113 and the new remainder 104, and apply the division lemma to get

113 = 104 x 1 + 9

We consider the new divisor 104 and the new remainder 9,and apply the division lemma to get

104 = 9 x 11 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 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 217 and 330 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(104,9) = HCF(113,104) = HCF(217,113) = HCF(330,217) .


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

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

658 = 1 x 658 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 658 is 1

Notice that 1 = HCF(658,1) .


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

Step 1: Since 331 > 1, we apply the division lemma to 331 and 1, to get

331 = 1 x 331 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 331 is 1

Notice that 1 = HCF(331,1) .
