HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 203, 778, 708, 17 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 203, 778, 708, 17 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 203, 778, 708, 17 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 203, 778, 708, 17 is 1.

HCF(203, 778, 708, 17) = 1

Highest common factor (HCF) of 203, 778, 708, 17 is 1.

Highest Common Factor of 203,778,708,17 using Euclid's algorithm

Highest Common Factor of 203,778,708,17 is 1

Step 1: Since 778 > 203, we apply the division lemma to 778 and 203, to get

778 = 203 x 3 + 169

Step 2: Since the reminder 203 ≠ 0, we apply division lemma to 169 and 203, to get

203 = 169 x 1 + 34

Step 3: We consider the new divisor 169 and the new remainder 34, and apply the division lemma to get

169 = 34 x 4 + 33

We consider the new divisor 34 and the new remainder 33,and apply the division lemma to get

34 = 33 x 1 + 1

We consider the new divisor 33 and the new remainder 1,and apply the division lemma to get

33 = 1 x 33 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 203 and 778 is 1

Notice that 1 = HCF(33,1) = HCF(34,33) = HCF(169,34) = HCF(203,169) = HCF(778,203) .


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

Step 1: Since 708 > 1, we apply the division lemma to 708 and 1, to get

708 = 1 x 708 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 708 is 1

Notice that 1 = HCF(708,1) .


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

Step 1: Since 17 > 1, we apply the division lemma to 17 and 1, to get

17 = 1 x 17 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 17 is 1

Notice that 1 = HCF(17,1) .
