HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 724, 1121 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 724, 1121 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, 1121 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, 1121 is 1.
HCF(724, 1121) = 1
HCF of 724, 1121 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, 1121 is 1.
Highest Common Factor of 724,1121 is 1
Step 1: Since 1121 > 724, we apply the division lemma to 1121 and 724, to get
1121 = 724 x 1 + 397
Step 2: Since the reminder 724 ≠ 0, we apply division lemma to 397 and 724, to get
724 = 397 x 1 + 327
Step 3: We consider the new divisor 397 and the new remainder 327, and apply the division lemma to get
397 = 327 x 1 + 70
We consider the new divisor 327 and the new remainder 70,and apply the division lemma to get
327 = 70 x 4 + 47
We consider the new divisor 70 and the new remainder 47,and apply the division lemma to get
70 = 47 x 1 + 23
We consider the new divisor 47 and the new remainder 23,and apply the division lemma to get
47 = 23 x 2 + 1
We consider the new divisor 23 and the new remainder 1,and apply the division lemma to get
23 = 1 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 724 and 1121 is 1
Notice that 1 = HCF(23,1) = HCF(47,23) = HCF(70,47) = HCF(327,70) = HCF(397,327) = HCF(724,397) = HCF(1121,724) .
