HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 864, 972 i.e. 108 the largest integer that leaves a remainder zero for all numbers.
HCF of 864, 972 is 108 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 864, 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 864, 972 is 108.
HCF(864, 972) = 108
HCF of 864, 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 864, 972 is 108.
Highest Common Factor of 864,972 is 108
Step 1: Since 972 > 864, we apply the division lemma to 972 and 864, to get
972 = 864 x 1 + 108
Step 2: Since the reminder 864 ≠ 0, we apply division lemma to 108 and 864, to get
864 = 108 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 108, the HCF of 864 and 972 is 108
Notice that 108 = HCF(864,108) = HCF(972,864) .
