HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 991, 889 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 991, 889 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 991, 889 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 991, 889 is 1.
HCF(991, 889) = 1
HCF of 991, 889 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 991, 889 is 1.
Highest Common Factor of 991,889 is 1
Step 1: Since 991 > 889, we apply the division lemma to 991 and 889, to get
991 = 889 x 1 + 102
Step 2: Since the reminder 889 ≠ 0, we apply division lemma to 102 and 889, to get
889 = 102 x 8 + 73
Step 3: We consider the new divisor 102 and the new remainder 73, and apply the division lemma to get
102 = 73 x 1 + 29
We consider the new divisor 73 and the new remainder 29,and apply the division lemma to get
73 = 29 x 2 + 15
We consider the new divisor 29 and the new remainder 15,and apply the division lemma to get
29 = 15 x 1 + 14
We consider the new divisor 15 and the new remainder 14,and apply the division lemma to get
15 = 14 x 1 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 991 and 889 is 1
Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(29,15) = HCF(73,29) = HCF(102,73) = HCF(889,102) = HCF(991,889) .
