HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 270, 161, 831 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 270, 161, 831 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 270, 161, 831 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 270, 161, 831 is 1.

HCF(270, 161, 831) = 1

Highest common factor (HCF) of 270, 161, 831 is 1.

Highest Common Factor of 270,161,831 using Euclid's algorithm

Highest Common Factor of 270,161,831 is 1

Step 1: Since 270 > 161, we apply the division lemma to 270 and 161, to get

270 = 161 x 1 + 109

Step 2: Since the reminder 161 ≠ 0, we apply division lemma to 109 and 161, to get

161 = 109 x 1 + 52

Step 3: We consider the new divisor 109 and the new remainder 52, and apply the division lemma to get

109 = 52 x 2 + 5

We consider the new divisor 52 and the new remainder 5,and apply the division lemma to get

52 = 5 x 10 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 270 and 161 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(52,5) = HCF(109,52) = HCF(161,109) = HCF(270,161) .

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

Step 1: Since 831 > 1, we apply the division lemma to 831 and 1, to get

831 = 1 x 831 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 831 is 1

Notice that 1 = HCF(831,1) .
