HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 778, 404 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 778, 404 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, 404 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, 404 is 2.
HCF(778, 404) = 2
HCF of 778, 404 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, 404 is 2.
Highest Common Factor of 778,404 is 2
Step 1: Since 778 > 404, we apply the division lemma to 778 and 404, to get
778 = 404 x 1 + 374
Step 2: Since the reminder 404 ≠ 0, we apply division lemma to 374 and 404, to get
404 = 374 x 1 + 30
Step 3: We consider the new divisor 374 and the new remainder 30, and apply the division lemma to get
374 = 30 x 12 + 14
We consider the new divisor 30 and the new remainder 14,and apply the division lemma to get
30 = 14 x 2 + 2
We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 778 and 404 is 2
Notice that 2 = HCF(14,2) = HCF(30,14) = HCF(374,30) = HCF(404,374) = HCF(778,404) .
