HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 678, 2988 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 678, 2988 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 678, 2988 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 678, 2988 is 6.
HCF(678, 2988) = 6
HCF of 678, 2988 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 678, 2988 is 6.
Highest Common Factor of 678,2988 is 6
Step 1: Since 2988 > 678, we apply the division lemma to 2988 and 678, to get
2988 = 678 x 4 + 276
Step 2: Since the reminder 678 ≠ 0, we apply division lemma to 276 and 678, to get
678 = 276 x 2 + 126
Step 3: We consider the new divisor 276 and the new remainder 126, and apply the division lemma to get
276 = 126 x 2 + 24
We consider the new divisor 126 and the new remainder 24,and apply the division lemma to get
126 = 24 x 5 + 6
We consider the new divisor 24 and the new remainder 6,and apply the division lemma to get
24 = 6 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 678 and 2988 is 6
Notice that 6 = HCF(24,6) = HCF(126,24) = HCF(276,126) = HCF(678,276) = HCF(2988,678) .
