HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 678, 928 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 678, 928 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 678, 928 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, 928 is 2.
HCF(678, 928) = 2
HCF of 678, 928 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, 928 is 2.
Highest Common Factor of 678,928 is 2
Step 1: Since 928 > 678, we apply the division lemma to 928 and 678, to get
928 = 678 x 1 + 250
Step 2: Since the reminder 678 ≠ 0, we apply division lemma to 250 and 678, to get
678 = 250 x 2 + 178
Step 3: We consider the new divisor 250 and the new remainder 178, and apply the division lemma to get
250 = 178 x 1 + 72
We consider the new divisor 178 and the new remainder 72,and apply the division lemma to get
178 = 72 x 2 + 34
We consider the new divisor 72 and the new remainder 34,and apply the division lemma to get
72 = 34 x 2 + 4
We consider the new divisor 34 and the new remainder 4,and apply the division lemma to get
34 = 4 x 8 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 678 and 928 is 2
Notice that 2 = HCF(4,2) = HCF(34,4) = HCF(72,34) = HCF(178,72) = HCF(250,178) = HCF(678,250) = HCF(928,678) .
