HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 778, 228 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 778, 228 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 778, 228 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 778, 228 is 2.
HCF(778, 228) = 2
HCF of 778, 228 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 778, 228 is 2.
Highest Common Factor of 778,228 is 2
Step 1: Since 778 > 228, we apply the division lemma to 778 and 228, to get
778 = 228 x 3 + 94
Step 2: Since the reminder 228 ≠ 0, we apply division lemma to 94 and 228, to get
228 = 94 x 2 + 40
Step 3: We consider the new divisor 94 and the new remainder 40, and apply the division lemma to get
94 = 40 x 2 + 14
We consider the new divisor 40 and the new remainder 14,and apply the division lemma to get
40 = 14 x 2 + 12
We consider the new divisor 14 and the new remainder 12,and apply the division lemma to get
14 = 12 x 1 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 778 and 228 is 2
Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(40,14) = HCF(94,40) = HCF(228,94) = HCF(778,228) .
