HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1985, 2549 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 1985, 2549 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 1985, 2549 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 1985, 2549 is 1.

HCF(1985, 2549) = 1

Highest common factor (HCF) of 1985, 2549 is 1.

Highest Common Factor of 1985,2549 using Euclid's algorithm

Highest Common Factor of 1985,2549 is 1

Step 1: Since 2549 > 1985, we apply the division lemma to 2549 and 1985, to get

2549 = 1985 x 1 + 564

Step 2: Since the reminder 1985 ≠ 0, we apply division lemma to 564 and 1985, to get

1985 = 564 x 3 + 293

Step 3: We consider the new divisor 564 and the new remainder 293, and apply the division lemma to get

564 = 293 x 1 + 271

We consider the new divisor 293 and the new remainder 271,and apply the division lemma to get

293 = 271 x 1 + 22

We consider the new divisor 271 and the new remainder 22,and apply the division lemma to get

271 = 22 x 12 + 7

We consider the new divisor 22 and the new remainder 7,and apply the division lemma to get

22 = 7 x 3 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1985 and 2549 is 1

Notice that 1 = HCF(7,1) = HCF(22,7) = HCF(271,22) = HCF(293,271) = HCF(564,293) = HCF(1985,564) = HCF(2549,1985) .
