HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 551, 957 i.e. 29 the largest integer that leaves a remainder zero for all numbers.
HCF of 551, 957 is 29 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 551, 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 551, 957 is 29.
HCF(551, 957) = 29
HCF of 551, 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 551, 957 is 29.
Highest Common Factor of 551,957 is 29
Step 1: Since 957 > 551, we apply the division lemma to 957 and 551, to get
957 = 551 x 1 + 406
Step 2: Since the reminder 551 ≠ 0, we apply division lemma to 406 and 551, to get
551 = 406 x 1 + 145
Step 3: We consider the new divisor 406 and the new remainder 145, and apply the division lemma to get
406 = 145 x 2 + 116
We consider the new divisor 145 and the new remainder 116,and apply the division lemma to get
145 = 116 x 1 + 29
We consider the new divisor 116 and the new remainder 29,and apply the division lemma to get
116 = 29 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 29, the HCF of 551 and 957 is 29
Notice that 29 = HCF(116,29) = HCF(145,116) = HCF(406,145) = HCF(551,406) = HCF(957,551) .
