HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 257, 157, 829 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 257, 157, 829 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 257, 157, 829 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 257, 157, 829 is 1.
HCF(257, 157, 829) = 1
HCF of 257, 157, 829 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 257, 157, 829 is 1.
Highest Common Factor of 257,157,829 is 1
Step 1: Since 257 > 157, we apply the division lemma to 257 and 157, to get
257 = 157 x 1 + 100
Step 2: Since the reminder 157 ≠ 0, we apply division lemma to 100 and 157, to get
157 = 100 x 1 + 57
Step 3: We consider the new divisor 100 and the new remainder 57, and apply the division lemma to get
100 = 57 x 1 + 43
We consider the new divisor 57 and the new remainder 43,and apply the division lemma to get
57 = 43 x 1 + 14
We consider the new divisor 43 and the new remainder 14,and apply the division lemma to get
43 = 14 x 3 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 257 and 157 is 1
Notice that 1 = HCF(14,1) = HCF(43,14) = HCF(57,43) = HCF(100,57) = HCF(157,100) = HCF(257,157) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 829 > 1, we apply the division lemma to 829 and 1, to get
829 = 1 x 829 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 829 is 1
Notice that 1 = HCF(829,1) .
