HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 161, 803, 136, 242 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 161, 803, 136, 242 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 161, 803, 136, 242 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 161, 803, 136, 242 is 1.

HCF(161, 803, 136, 242) = 1

Highest Common Factor of 161,803,136,242 using Euclid's algorithm

Highest Common Factor of 161,803,136,242 is 1

Step 1: Since 803 > 161, we apply the division lemma to 803 and 161, to get

803 = 161 x 4 + 159

Step 2: Since the reminder 161 ≠ 0, we apply division lemma to 159 and 161, to get

161 = 159 x 1 + 2

Step 3: We consider the new divisor 159 and the new remainder 2, and apply the division lemma to get

159 = 2 x 79 + 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 161 and 803 is 1

Notice that 1 = HCF(2,1) = HCF(159,2) = HCF(161,159) = HCF(803,161) .


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

Step 1: Since 136 > 1, we apply the division lemma to 136 and 1, to get

136 = 1 x 136 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 136 is 1

Notice that 1 = HCF(136,1) .


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

Step 1: Since 242 > 1, we apply the division lemma to 242 and 1, to get

242 = 1 x 242 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 242 is 1

Notice that 1 = HCF(242,1) .
