HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 615, 773 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 615, 773 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 615, 773 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 615, 773 is 1.
HCF(615, 773) = 1
HCF of 615, 773 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 615, 773 is 1.
Highest Common Factor of 615,773 is 1
Step 1: Since 773 > 615, we apply the division lemma to 773 and 615, to get
773 = 615 x 1 + 158
Step 2: Since the reminder 615 ≠ 0, we apply division lemma to 158 and 615, to get
615 = 158 x 3 + 141
Step 3: We consider the new divisor 158 and the new remainder 141, and apply the division lemma to get
158 = 141 x 1 + 17
We consider the new divisor 141 and the new remainder 17,and apply the division lemma to get
141 = 17 x 8 + 5
We consider the new divisor 17 and the new remainder 5,and apply the division lemma to get
17 = 5 x 3 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 615 and 773 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(17,5) = HCF(141,17) = HCF(158,141) = HCF(615,158) = HCF(773,615) .
