HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 4989, 7042 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 4989, 7042 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 4989, 7042 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 4989, 7042 is 1.

HCF(4989, 7042) = 1

Highest Common Factor of 4989,7042 using Euclid's algorithm

Highest Common Factor of 4989,7042 is 1

Step 1: Since 7042 > 4989, we apply the division lemma to 7042 and 4989, to get

7042 = 4989 x 1 + 2053

Step 2: Since the reminder 4989 ≠ 0, we apply division lemma to 2053 and 4989, to get

4989 = 2053 x 2 + 883

Step 3: We consider the new divisor 2053 and the new remainder 883, and apply the division lemma to get

2053 = 883 x 2 + 287

We consider the new divisor 883 and the new remainder 287,and apply the division lemma to get

883 = 287 x 3 + 22

We consider the new divisor 287 and the new remainder 22,and apply the division lemma to get

287 = 22 x 13 + 1

We consider the new divisor 22 and the new remainder 1,and apply the division lemma to get

22 = 1 x 22 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4989 and 7042 is 1

Notice that 1 = HCF(22,1) = HCF(287,22) = HCF(883,287) = HCF(2053,883) = HCF(4989,2053) = HCF(7042,4989) .
