HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 620, 522, 317 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 620, 522, 317 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 620, 522, 317 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 620, 522, 317 is 1.
HCF(620, 522, 317) = 1
HCF of 620, 522, 317 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 620, 522, 317 is 1.
Highest Common Factor of 620,522,317 is 1
Step 1: Since 620 > 522, we apply the division lemma to 620 and 522, to get
620 = 522 x 1 + 98
Step 2: Since the reminder 522 ≠ 0, we apply division lemma to 98 and 522, to get
522 = 98 x 5 + 32
Step 3: We consider the new divisor 98 and the new remainder 32, and apply the division lemma to get
98 = 32 x 3 + 2
We consider the new divisor 32 and the new remainder 2, and apply the division lemma to get
32 = 2 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 620 and 522 is 2
Notice that 2 = HCF(32,2) = HCF(98,32) = HCF(522,98) = HCF(620,522) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 317 > 2, we apply the division lemma to 317 and 2, to get
317 = 2 x 158 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 317 is 1
Notice that 1 = HCF(2,1) = HCF(317,2) .
