HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 215, 764 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 215, 764 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 215, 764 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 215, 764 is 1.
HCF(215, 764) = 1
HCF of 215, 764 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 215, 764 is 1.
Highest Common Factor of 215,764 is 1
Step 1: Since 764 > 215, we apply the division lemma to 764 and 215, to get
764 = 215 x 3 + 119
Step 2: Since the reminder 215 ≠ 0, we apply division lemma to 119 and 215, to get
215 = 119 x 1 + 96
Step 3: We consider the new divisor 119 and the new remainder 96, and apply the division lemma to get
119 = 96 x 1 + 23
We consider the new divisor 96 and the new remainder 23,and apply the division lemma to get
96 = 23 x 4 + 4
We consider the new divisor 23 and the new remainder 4,and apply the division lemma to get
23 = 4 x 5 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 215 and 764 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(23,4) = HCF(96,23) = HCF(119,96) = HCF(215,119) = HCF(764,215) .
