HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 978, 538 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 978, 538 is 2 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 978, 538 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 978, 538 is 2.
HCF(978, 538) = 2
HCF of 978, 538 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 978, 538 is 2.
Highest Common Factor of 978,538 is 2
Step 1: Since 978 > 538, we apply the division lemma to 978 and 538, to get
978 = 538 x 1 + 440
Step 2: Since the reminder 538 ≠ 0, we apply division lemma to 440 and 538, to get
538 = 440 x 1 + 98
Step 3: We consider the new divisor 440 and the new remainder 98, and apply the division lemma to get
440 = 98 x 4 + 48
We consider the new divisor 98 and the new remainder 48,and apply the division lemma to get
98 = 48 x 2 + 2
We consider the new divisor 48 and the new remainder 2,and apply the division lemma to get
48 = 2 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 978 and 538 is 2
Notice that 2 = HCF(48,2) = HCF(98,48) = HCF(440,98) = HCF(538,440) = HCF(978,538) .
