HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 407, 302, 644, 173 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 407, 302, 644, 173 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 407, 302, 644, 173 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 407, 302, 644, 173 is 1.

HCF(407, 302, 644, 173) = 1

Highest Common Factor of 407,302,644,173 using Euclid's algorithm

Highest Common Factor of 407,302,644,173 is 1

Step 1: Since 407 > 302, we apply the division lemma to 407 and 302, to get

407 = 302 x 1 + 105

Step 2: Since the reminder 302 ≠ 0, we apply division lemma to 105 and 302, to get

302 = 105 x 2 + 92

Step 3: We consider the new divisor 105 and the new remainder 92, and apply the division lemma to get

105 = 92 x 1 + 13

We consider the new divisor 92 and the new remainder 13,and apply the division lemma to get

92 = 13 x 7 + 1

We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 407 and 302 is 1

Notice that 1 = HCF(13,1) = HCF(92,13) = HCF(105,92) = HCF(302,105) = HCF(407,302) .


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

Step 1: Since 644 > 1, we apply the division lemma to 644 and 1, to get

644 = 1 x 644 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 644 is 1

Notice that 1 = HCF(644,1) .


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

Step 1: Since 173 > 1, we apply the division lemma to 173 and 1, to get

173 = 1 x 173 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 173 is 1

Notice that 1 = HCF(173,1) .
