HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 170, 791, 395, 32 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 170, 791, 395, 32 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 170, 791, 395, 32 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 170, 791, 395, 32 is 1.

HCF(170, 791, 395, 32) = 1

Highest Common Factor of 170,791,395,32 using Euclid's algorithm

Highest Common Factor of 170,791,395,32 is 1

Step 1: Since 791 > 170, we apply the division lemma to 791 and 170, to get

791 = 170 x 4 + 111

Step 2: Since the reminder 170 ≠ 0, we apply division lemma to 111 and 170, to get

170 = 111 x 1 + 59

Step 3: We consider the new divisor 111 and the new remainder 59, and apply the division lemma to get

111 = 59 x 1 + 52

We consider the new divisor 59 and the new remainder 52,and apply the division lemma to get

59 = 52 x 1 + 7

We consider the new divisor 52 and the new remainder 7,and apply the division lemma to get

52 = 7 x 7 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 170 and 791 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(52,7) = HCF(59,52) = HCF(111,59) = HCF(170,111) = HCF(791,170) .

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

Step 1: Since 395 > 1, we apply the division lemma to 395 and 1, to get

395 = 1 x 395 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 395 is 1

Notice that 1 = HCF(395,1) .

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

Step 1: Since 32 > 1, we apply the division lemma to 32 and 1, to get

32 = 1 x 32 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 32 is 1

Notice that 1 = HCF(32,1) .
