HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 522, 684 i.e. 18 the largest integer that leaves a remainder zero for all numbers.
HCF of 522, 684 is 18 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 522, 684 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 522, 684 is 18.
HCF(522, 684) = 18
HCF of 522, 684 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 522, 684 is 18.
Highest Common Factor of 522,684 is 18
Step 1: Since 684 > 522, we apply the division lemma to 684 and 522, to get
684 = 522 x 1 + 162
Step 2: Since the reminder 522 ≠ 0, we apply division lemma to 162 and 522, to get
522 = 162 x 3 + 36
Step 3: We consider the new divisor 162 and the new remainder 36, and apply the division lemma to get
162 = 36 x 4 + 18
We consider the new divisor 36 and the new remainder 18, and apply the division lemma to get
36 = 18 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 522 and 684 is 18
Notice that 18 = HCF(36,18) = HCF(162,36) = HCF(522,162) = HCF(684,522) .
