HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 718, 564 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 497, 718, 564 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, 718, 564 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, 718, 564 is 1.
HCF(497, 718, 564) = 1
HCF of 497, 718, 564 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 497, 718, 564 is 1.
Highest Common Factor of 497,718,564 is 1
Step 1: Since 718 > 497, we apply the division lemma to 718 and 497, to get
718 = 497 x 1 + 221
Step 2: Since the reminder 497 ≠ 0, we apply division lemma to 221 and 497, to get
497 = 221 x 2 + 55
Step 3: We consider the new divisor 221 and the new remainder 55, and apply the division lemma to get
221 = 55 x 4 + 1
We consider the new divisor 55 and the new remainder 1, and apply the division lemma to get
55 = 1 x 55 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 497 and 718 is 1
Notice that 1 = HCF(55,1) = HCF(221,55) = HCF(497,221) = HCF(718,497) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 564 > 1, we apply the division lemma to 564 and 1, to get
564 = 1 x 564 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 564 is 1
Notice that 1 = HCF(564,1) .
