HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 728, 975 i.e. 13 the largest integer that leaves a remainder zero for all numbers.
HCF of 728, 975 is 13 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 728, 975 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 728, 975 is 13.
HCF(728, 975) = 13
HCF of 728, 975 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 728, 975 is 13.
Highest Common Factor of 728,975 is 13
Step 1: Since 975 > 728, we apply the division lemma to 975 and 728, to get
975 = 728 x 1 + 247
Step 2: Since the reminder 728 ≠ 0, we apply division lemma to 247 and 728, to get
728 = 247 x 2 + 234
Step 3: We consider the new divisor 247 and the new remainder 234, and apply the division lemma to get
247 = 234 x 1 + 13
We consider the new divisor 234 and the new remainder 13, and apply the division lemma to get
234 = 13 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 728 and 975 is 13
Notice that 13 = HCF(234,13) = HCF(247,234) = HCF(728,247) = HCF(975,728) .
