HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 917, 601, 243 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 917, 601, 243 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 917, 601, 243 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 917, 601, 243 is 1.

HCF(917, 601, 243) = 1

Highest common factor (HCF) of 917, 601, 243 is 1.

Highest Common Factor of 917,601,243 using Euclid's algorithm

Highest Common Factor of 917,601,243 is 1

Step 1: Since 917 > 601, we apply the division lemma to 917 and 601, to get

917 = 601 x 1 + 316

Step 2: Since the reminder 601 ≠ 0, we apply division lemma to 316 and 601, to get

601 = 316 x 1 + 285

Step 3: We consider the new divisor 316 and the new remainder 285, and apply the division lemma to get

316 = 285 x 1 + 31

We consider the new divisor 285 and the new remainder 31,and apply the division lemma to get

285 = 31 x 9 + 6

We consider the new divisor 31 and the new remainder 6,and apply the division lemma to get

31 = 6 x 5 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 917 and 601 is 1

Notice that 1 = HCF(6,1) = HCF(31,6) = HCF(285,31) = HCF(316,285) = HCF(601,316) = HCF(917,601) .

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

Step 1: Since 243 > 1, we apply the division lemma to 243 and 1, to get

243 = 1 x 243 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 243 is 1

Notice that 1 = HCF(243,1) .
