HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 997, 42525 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 997, 42525 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 997, 42525 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 997, 42525 is 1.

HCF(997, 42525) = 1

Highest common factor (HCF) of 997, 42525 is 1.

Highest Common Factor of 997,42525 using Euclid's algorithm

Highest Common Factor of 997,42525 is 1

Step 1: Since 42525 > 997, we apply the division lemma to 42525 and 997, to get

42525 = 997 x 42 + 651

Step 2: Since the reminder 997 ≠ 0, we apply division lemma to 651 and 997, to get

997 = 651 x 1 + 346

Step 3: We consider the new divisor 651 and the new remainder 346, and apply the division lemma to get

651 = 346 x 1 + 305

We consider the new divisor 346 and the new remainder 305,and apply the division lemma to get

346 = 305 x 1 + 41

We consider the new divisor 305 and the new remainder 41,and apply the division lemma to get

305 = 41 x 7 + 18

We consider the new divisor 41 and the new remainder 18,and apply the division lemma to get

41 = 18 x 2 + 5

We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get

18 = 5 x 3 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 997 and 42525 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(41,18) = HCF(305,41) = HCF(346,305) = HCF(651,346) = HCF(997,651) = HCF(42525,997) .
