HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 869, 972 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 869, 972 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 869, 972 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 869, 972 is 1.
HCF(869, 972) = 1
HCF of 869, 972 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 869, 972 is 1.
Highest Common Factor of 869,972 is 1
Step 1: Since 972 > 869, we apply the division lemma to 972 and 869, to get
972 = 869 x 1 + 103
Step 2: Since the reminder 869 ≠ 0, we apply division lemma to 103 and 869, to get
869 = 103 x 8 + 45
Step 3: We consider the new divisor 103 and the new remainder 45, and apply the division lemma to get
103 = 45 x 2 + 13
We consider the new divisor 45 and the new remainder 13,and apply the division lemma to get
45 = 13 x 3 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 869 and 972 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(45,13) = HCF(103,45) = HCF(869,103) = HCF(972,869) .
