HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 797, 523, 256, 505 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 797, 523, 256, 505 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 797, 523, 256, 505 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 797, 523, 256, 505 is 1.
HCF(797, 523, 256, 505) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 797, 523, 256, 505 is 1.
Step 1: Since 797 > 523, we apply the division lemma to 797 and 523, to get
797 = 523 x 1 + 274
Step 2: Since the reminder 523 ≠ 0, we apply division lemma to 274 and 523, to get
523 = 274 x 1 + 249
Step 3: We consider the new divisor 274 and the new remainder 249, and apply the division lemma to get
274 = 249 x 1 + 25
We consider the new divisor 249 and the new remainder 25,and apply the division lemma to get
249 = 25 x 9 + 24
We consider the new divisor 25 and the new remainder 24,and apply the division lemma to get
25 = 24 x 1 + 1
We consider the new divisor 24 and the new remainder 1,and apply the division lemma to get
24 = 1 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 797 and 523 is 1
Notice that 1 = HCF(24,1) = HCF(25,24) = HCF(249,25) = HCF(274,249) = HCF(523,274) = HCF(797,523) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 256 > 1, we apply the division lemma to 256 and 1, to get
256 = 1 x 256 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 256 is 1
Notice that 1 = HCF(256,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 505 > 1, we apply the division lemma to 505 and 1, to get
505 = 1 x 505 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 505 is 1
Notice that 1 = HCF(505,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
