HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 977, 719 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 977, 719 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, 719 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, 719 is 1.
HCF(977, 719) = 1
HCF of 977, 719 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, 719 is 1.
Highest Common Factor of 977,719 is 1
Step 1: Since 977 > 719, we apply the division lemma to 977 and 719, to get
977 = 719 x 1 + 258
Step 2: Since the reminder 719 ≠ 0, we apply division lemma to 258 and 719, to get
719 = 258 x 2 + 203
Step 3: We consider the new divisor 258 and the new remainder 203, and apply the division lemma to get
258 = 203 x 1 + 55
We consider the new divisor 203 and the new remainder 55,and apply the division lemma to get
203 = 55 x 3 + 38
We consider the new divisor 55 and the new remainder 38,and apply the division lemma to get
55 = 38 x 1 + 17
We consider the new divisor 38 and the new remainder 17,and apply the division lemma to get
38 = 17 x 2 + 4
We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get
17 = 4 x 4 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 977 and 719 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(38,17) = HCF(55,38) = HCF(203,55) = HCF(258,203) = HCF(719,258) = HCF(977,719) .
