HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 646, 227, 776 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 646, 227, 776 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 646, 227, 776 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 646, 227, 776 is 1.
HCF(646, 227, 776) = 1
HCF of 646, 227, 776 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 646, 227, 776 is 1.
Highest Common Factor of 646,227,776 is 1
Step 1: Since 646 > 227, we apply the division lemma to 646 and 227, to get
646 = 227 x 2 + 192
Step 2: Since the reminder 227 ≠ 0, we apply division lemma to 192 and 227, to get
227 = 192 x 1 + 35
Step 3: We consider the new divisor 192 and the new remainder 35, and apply the division lemma to get
192 = 35 x 5 + 17
We consider the new divisor 35 and the new remainder 17,and apply the division lemma to get
35 = 17 x 2 + 1
We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 646 and 227 is 1
Notice that 1 = HCF(17,1) = HCF(35,17) = HCF(192,35) = HCF(227,192) = HCF(646,227) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 776 > 1, we apply the division lemma to 776 and 1, to get
776 = 1 x 776 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 776 is 1
Notice that 1 = HCF(776,1) .
