HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 255, 178, 260 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 255, 178, 260 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 255, 178, 260 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 255, 178, 260 is 1.

HCF(255, 178, 260) = 1

Highest common factor (HCF) of 255, 178, 260 is 1.

Highest Common Factor of 255,178,260 using Euclid's algorithm

Highest Common Factor of 255,178,260 is 1

Step 1: Since 255 > 178, we apply the division lemma to 255 and 178, to get

255 = 178 x 1 + 77

Step 2: Since the reminder 178 ≠ 0, we apply division lemma to 77 and 178, to get

178 = 77 x 2 + 24

Step 3: We consider the new divisor 77 and the new remainder 24, and apply the division lemma to get

77 = 24 x 3 + 5

We consider the new divisor 24 and the new remainder 5,and apply the division lemma to get

24 = 5 x 4 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 255 and 178 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) = HCF(77,24) = HCF(178,77) = HCF(255,178) .

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

Step 1: Since 260 > 1, we apply the division lemma to 260 and 1, to get

260 = 1 x 260 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 260 is 1

Notice that 1 = HCF(260,1) .
