HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 957, 57165 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 957, 57165 is 3 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 957, 57165 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 957, 57165 is 3.
HCF(957, 57165) = 3
HCF of 957, 57165 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 957, 57165 is 3.
Highest Common Factor of 957,57165 is 3
Step 1: Since 57165 > 957, we apply the division lemma to 57165 and 957, to get
57165 = 957 x 59 + 702
Step 2: Since the reminder 957 ≠ 0, we apply division lemma to 702 and 957, to get
957 = 702 x 1 + 255
Step 3: We consider the new divisor 702 and the new remainder 255, and apply the division lemma to get
702 = 255 x 2 + 192
We consider the new divisor 255 and the new remainder 192,and apply the division lemma to get
255 = 192 x 1 + 63
We consider the new divisor 192 and the new remainder 63,and apply the division lemma to get
192 = 63 x 3 + 3
We consider the new divisor 63 and the new remainder 3,and apply the division lemma to get
63 = 3 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 957 and 57165 is 3
Notice that 3 = HCF(63,3) = HCF(192,63) = HCF(255,192) = HCF(702,255) = HCF(957,702) = HCF(57165,957) .
