HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 515, 777 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 515, 777 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 515, 777 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 515, 777 is 1.
HCF(515, 777) = 1
HCF of 515, 777 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 515, 777 is 1.
Highest Common Factor of 515,777 is 1
Step 1: Since 777 > 515, we apply the division lemma to 777 and 515, to get
777 = 515 x 1 + 262
Step 2: Since the reminder 515 ≠ 0, we apply division lemma to 262 and 515, to get
515 = 262 x 1 + 253
Step 3: We consider the new divisor 262 and the new remainder 253, and apply the division lemma to get
262 = 253 x 1 + 9
We consider the new divisor 253 and the new remainder 9,and apply the division lemma to get
253 = 9 x 28 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 515 and 777 is 1
Notice that 1 = HCF(9,1) = HCF(253,9) = HCF(262,253) = HCF(515,262) = HCF(777,515) .
