HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 977, 261, 745 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 977, 261, 745 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 977, 261, 745 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 977, 261, 745 is 1.
HCF(977, 261, 745) = 1
HCF of 977, 261, 745 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 977, 261, 745 is 1.
Highest Common Factor of 977,261,745 is 1
Step 1: Since 977 > 261, we apply the division lemma to 977 and 261, to get
977 = 261 x 3 + 194
Step 2: Since the reminder 261 ≠ 0, we apply division lemma to 194 and 261, to get
261 = 194 x 1 + 67
Step 3: We consider the new divisor 194 and the new remainder 67, and apply the division lemma to get
194 = 67 x 2 + 60
We consider the new divisor 67 and the new remainder 60,and apply the division lemma to get
67 = 60 x 1 + 7
We consider the new divisor 60 and the new remainder 7,and apply the division lemma to get
60 = 7 x 8 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 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 977 and 261 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(60,7) = HCF(67,60) = HCF(194,67) = HCF(261,194) = HCF(977,261) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 745 > 1, we apply the division lemma to 745 and 1, to get
745 = 1 x 745 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 745 is 1
Notice that 1 = HCF(745,1) .
