HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 802, 295 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 497, 802, 295 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 497, 802, 295 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 497, 802, 295 is 1.
HCF(497, 802, 295) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 497, 802, 295 is 1.
Step 1: Since 802 > 497, we apply the division lemma to 802 and 497, to get
802 = 497 x 1 + 305
Step 2: Since the reminder 497 ≠ 0, we apply division lemma to 305 and 497, to get
497 = 305 x 1 + 192
Step 3: We consider the new divisor 305 and the new remainder 192, and apply the division lemma to get
305 = 192 x 1 + 113
We consider the new divisor 192 and the new remainder 113,and apply the division lemma to get
192 = 113 x 1 + 79
We consider the new divisor 113 and the new remainder 79,and apply the division lemma to get
113 = 79 x 1 + 34
We consider the new divisor 79 and the new remainder 34,and apply the division lemma to get
79 = 34 x 2 + 11
We consider the new divisor 34 and the new remainder 11,and apply the division lemma to get
34 = 11 x 3 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 497 and 802 is 1
Notice that 1 = HCF(11,1) = HCF(34,11) = HCF(79,34) = HCF(113,79) = HCF(192,113) = HCF(305,192) = HCF(497,305) = HCF(802,497) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 295 > 1, we apply the division lemma to 295 and 1, to get
295 = 1 x 295 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 295 is 1
Notice that 1 = HCF(295,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
