HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 257, 934, 152 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 257, 934, 152 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, 934, 152 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, 934, 152 is 1.
HCF(257, 934, 152) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 257, 934, 152 is 1.
Step 1: Since 934 > 257, we apply the division lemma to 934 and 257, to get
934 = 257 x 3 + 163
Step 2: Since the reminder 257 ≠ 0, we apply division lemma to 163 and 257, to get
257 = 163 x 1 + 94
Step 3: We consider the new divisor 163 and the new remainder 94, and apply the division lemma to get
163 = 94 x 1 + 69
We consider the new divisor 94 and the new remainder 69,and apply the division lemma to get
94 = 69 x 1 + 25
We consider the new divisor 69 and the new remainder 25,and apply the division lemma to get
69 = 25 x 2 + 19
We consider the new divisor 25 and the new remainder 19,and apply the division lemma to get
25 = 19 x 1 + 6
We consider the new divisor 19 and the new remainder 6,and apply the division lemma to get
19 = 6 x 3 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 257 and 934 is 1
Notice that 1 = HCF(6,1) = HCF(19,6) = HCF(25,19) = HCF(69,25) = HCF(94,69) = HCF(163,94) = HCF(257,163) = HCF(934,257) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 152 > 1, we apply the division lemma to 152 and 1, to get
152 = 1 x 152 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 152 is 1
Notice that 1 = HCF(152,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
