HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 525, 693 i.e. 21 the largest integer that leaves a remainder zero for all numbers.
HCF of 525, 693 is 21 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 525, 693 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 525, 693 is 21.
HCF(525, 693) = 21
HCF of 525, 693 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 525, 693 is 21.
Highest Common Factor of 525,693 is 21
Step 1: Since 693 > 525, we apply the division lemma to 693 and 525, to get
693 = 525 x 1 + 168
Step 2: Since the reminder 525 ≠ 0, we apply division lemma to 168 and 525, to get
525 = 168 x 3 + 21
Step 3: We consider the new divisor 168 and the new remainder 21, and apply the division lemma to get
168 = 21 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 21, the HCF of 525 and 693 is 21
Notice that 21 = HCF(168,21) = HCF(525,168) = HCF(693,525) .
