HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 724, 917 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 724, 917 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 724, 917 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 724, 917 is 1.
HCF(724, 917) = 1
HCF of 724, 917 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 724, 917 is 1.
Highest Common Factor of 724,917 is 1
Step 1: Since 917 > 724, we apply the division lemma to 917 and 724, to get
917 = 724 x 1 + 193
Step 2: Since the reminder 724 ≠ 0, we apply division lemma to 193 and 724, to get
724 = 193 x 3 + 145
Step 3: We consider the new divisor 193 and the new remainder 145, and apply the division lemma to get
193 = 145 x 1 + 48
We consider the new divisor 145 and the new remainder 48,and apply the division lemma to get
145 = 48 x 3 + 1
We consider the new divisor 48 and the new remainder 1,and apply the division lemma to get
48 = 1 x 48 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 724 and 917 is 1
Notice that 1 = HCF(48,1) = HCF(145,48) = HCF(193,145) = HCF(724,193) = HCF(917,724) .
