HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 297, 551, 967, 149 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 297, 551, 967, 149 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 297, 551, 967, 149 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 297, 551, 967, 149 is 1.

HCF(297, 551, 967, 149) = 1

Highest Common Factor of 297,551,967,149 using Euclid's algorithm

Highest Common Factor of 297,551,967,149 is 1

Step 1: Since 551 > 297, we apply the division lemma to 551 and 297, to get

551 = 297 x 1 + 254

Step 2: Since the reminder 297 ≠ 0, we apply division lemma to 254 and 297, to get

297 = 254 x 1 + 43

Step 3: We consider the new divisor 254 and the new remainder 43, and apply the division lemma to get

254 = 43 x 5 + 39

We consider the new divisor 43 and the new remainder 39,and apply the division lemma to get

43 = 39 x 1 + 4

We consider the new divisor 39 and the new remainder 4,and apply the division lemma to get

39 = 4 x 9 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 297 and 551 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(39,4) = HCF(43,39) = HCF(254,43) = HCF(297,254) = HCF(551,297) .

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

Step 1: Since 967 > 1, we apply the division lemma to 967 and 1, to get

967 = 1 x 967 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 967 is 1

Notice that 1 = HCF(967,1) .

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

Step 1: Since 149 > 1, we apply the division lemma to 149 and 1, to get

149 = 1 x 149 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 149 is 1

Notice that 1 = HCF(149,1) .
