HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 154, 297 i.e. 11 the largest integer that leaves a remainder zero for all numbers.

HCF of 154, 297 is 11 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 154, 297 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 154, 297 is 11.

HCF(154, 297) = 11

Highest common factor (HCF) of 154, 297 is 11.

Highest Common Factor of 154,297 using Euclid's algorithm

Highest Common Factor of 154,297 is 11

Step 1: Since 297 > 154, we apply the division lemma to 297 and 154, to get

297 = 154 x 1 + 143

Step 2: Since the reminder 154 ≠ 0, we apply division lemma to 143 and 154, to get

154 = 143 x 1 + 11

Step 3: We consider the new divisor 143 and the new remainder 11, and apply the division lemma to get

143 = 11 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 154 and 297 is 11

Notice that 11 = HCF(143,11) = HCF(154,143) = HCF(297,154) .
