HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 478, 765 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 478, 765 is 1 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 478, 765 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 478, 765 is 1.
HCF(478, 765) = 1
HCF of 478, 765 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 478, 765 is 1.
Highest Common Factor of 478,765 is 1
Step 1: Since 765 > 478, we apply the division lemma to 765 and 478, to get
765 = 478 x 1 + 287
Step 2: Since the reminder 478 ≠ 0, we apply division lemma to 287 and 478, to get
478 = 287 x 1 + 191
Step 3: We consider the new divisor 287 and the new remainder 191, and apply the division lemma to get
287 = 191 x 1 + 96
We consider the new divisor 191 and the new remainder 96,and apply the division lemma to get
191 = 96 x 1 + 95
We consider the new divisor 96 and the new remainder 95,and apply the division lemma to get
96 = 95 x 1 + 1
We consider the new divisor 95 and the new remainder 1,and apply the division lemma to get
95 = 1 x 95 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 478 and 765 is 1
Notice that 1 = HCF(95,1) = HCF(96,95) = HCF(191,96) = HCF(287,191) = HCF(478,287) = HCF(765,478) .
