HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 309, 188, 631, 185 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 309, 188, 631, 185 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 309, 188, 631, 185 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 309, 188, 631, 185 is 1.

HCF(309, 188, 631, 185) = 1

Highest Common Factor of 309,188,631,185 using Euclid's algorithm

Highest Common Factor of 309,188,631,185 is 1

Step 1: Since 309 > 188, we apply the division lemma to 309 and 188, to get

309 = 188 x 1 + 121

Step 2: Since the reminder 188 ≠ 0, we apply division lemma to 121 and 188, to get

188 = 121 x 1 + 67

Step 3: We consider the new divisor 121 and the new remainder 67, and apply the division lemma to get

121 = 67 x 1 + 54

We consider the new divisor 67 and the new remainder 54,and apply the division lemma to get

67 = 54 x 1 + 13

We consider the new divisor 54 and the new remainder 13,and apply the division lemma to get

54 = 13 x 4 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 309 and 188 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(54,13) = HCF(67,54) = HCF(121,67) = HCF(188,121) = HCF(309,188) .


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

Step 1: Since 631 > 1, we apply the division lemma to 631 and 1, to get

631 = 1 x 631 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 631 is 1

Notice that 1 = HCF(631,1) .


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

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

185 = 1 x 185 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 185 is 1

Notice that 1 = HCF(185,1) .
