HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 978, 264 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 978, 264 is 6 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, 264 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, 264 is 6.
HCF(978, 264) = 6
HCF of 978, 264 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, 264 is 6.
Highest Common Factor of 978,264 is 6
Step 1: Since 978 > 264, we apply the division lemma to 978 and 264, to get
978 = 264 x 3 + 186
Step 2: Since the reminder 264 ≠ 0, we apply division lemma to 186 and 264, to get
264 = 186 x 1 + 78
Step 3: We consider the new divisor 186 and the new remainder 78, and apply the division lemma to get
186 = 78 x 2 + 30
We consider the new divisor 78 and the new remainder 30,and apply the division lemma to get
78 = 30 x 2 + 18
We consider the new divisor 30 and the new remainder 18,and apply the division lemma to get
30 = 18 x 1 + 12
We consider the new divisor 18 and the new remainder 12,and apply the division lemma to get
18 = 12 x 1 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 978 and 264 is 6
Notice that 6 = HCF(12,6) = HCF(18,12) = HCF(30,18) = HCF(78,30) = HCF(186,78) = HCF(264,186) = HCF(978,264) .
