HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 166, 602, 31, 317 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 166, 602, 31, 317 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 166, 602, 31, 317 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 166, 602, 31, 317 is 1.

HCF(166, 602, 31, 317) = 1

Highest common factor (HCF) of 166, 602, 31, 317 is 1.

Highest Common Factor of 166,602,31,317 using Euclid's algorithm

Highest Common Factor of 166,602,31,317 is 1

Step 1: Since 602 > 166, we apply the division lemma to 602 and 166, to get

602 = 166 x 3 + 104

Step 2: Since the reminder 166 ≠ 0, we apply division lemma to 104 and 166, to get

166 = 104 x 1 + 62

Step 3: We consider the new divisor 104 and the new remainder 62, and apply the division lemma to get

104 = 62 x 1 + 42

We consider the new divisor 62 and the new remainder 42,and apply the division lemma to get

62 = 42 x 1 + 20

We consider the new divisor 42 and the new remainder 20,and apply the division lemma to get

42 = 20 x 2 + 2

We consider the new divisor 20 and the new remainder 2,and apply the division lemma to get

20 = 2 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 166 and 602 is 2

Notice that 2 = HCF(20,2) = HCF(42,20) = HCF(62,42) = HCF(104,62) = HCF(166,104) = HCF(602,166) .


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

Step 1: Since 31 > 2, we apply the division lemma to 31 and 2, to get

31 = 2 x 15 + 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 31 is 1

Notice that 1 = HCF(2,1) = HCF(31,2) .


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

Step 1: Since 317 > 1, we apply the division lemma to 317 and 1, to get

317 = 1 x 317 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 317 is 1

Notice that 1 = HCF(317,1) .
