HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 64, 85, 53, 503 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 64, 85, 53, 503 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 64, 85, 53, 503 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 64, 85, 53, 503 is 1.
HCF(64, 85, 53, 503) = 1
HCF of 64, 85, 53, 503 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 64, 85, 53, 503 is 1.
Highest Common Factor of 64,85,53,503 is 1
Step 1: Since 85 > 64, we apply the division lemma to 85 and 64, to get
85 = 64 x 1 + 21
Step 2: Since the reminder 64 ≠ 0, we apply division lemma to 21 and 64, to get
64 = 21 x 3 + 1
Step 3: We consider the new divisor 21 and the new remainder 1, and apply the division lemma to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 64 and 85 is 1
Notice that 1 = HCF(21,1) = HCF(64,21) = HCF(85,64) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 53 > 1, we apply the division lemma to 53 and 1, to get
53 = 1 x 53 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 53 is 1
Notice that 1 = HCF(53,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 503 > 1, we apply the division lemma to 503 and 1, to get
503 = 1 x 503 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 503 is 1
Notice that 1 = HCF(503,1) .
