HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 728, 957 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 728, 957 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 728, 957 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, 957 is 1.
HCF(728, 957) = 1
HCF of 728, 957 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, 957 is 1.
Highest Common Factor of 728,957 is 1
Step 1: Since 957 > 728, we apply the division lemma to 957 and 728, to get
957 = 728 x 1 + 229
Step 2: Since the reminder 728 ≠ 0, we apply division lemma to 229 and 728, to get
728 = 229 x 3 + 41
Step 3: We consider the new divisor 229 and the new remainder 41, and apply the division lemma to get
229 = 41 x 5 + 24
We consider the new divisor 41 and the new remainder 24,and apply the division lemma to get
41 = 24 x 1 + 17
We consider the new divisor 24 and the new remainder 17,and apply the division lemma to get
24 = 17 x 1 + 7
We consider the new divisor 17 and the new remainder 7,and apply the division lemma to get
17 = 7 x 2 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 728 and 957 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(17,7) = HCF(24,17) = HCF(41,24) = HCF(229,41) = HCF(728,229) = HCF(957,728) .
