HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 723, 30 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 723, 30 is 3 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 723, 30 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 723, 30 is 3.
HCF(723, 30) = 3
HCF of 723, 30 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 723, 30 is 3.
Highest Common Factor of 723,30 is 3
Step 1: Since 723 > 30, we apply the division lemma to 723 and 30, to get
723 = 30 x 24 + 3
Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 3 and 30, to get
30 = 3 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 723 and 30 is 3
Notice that 3 = HCF(30,3) = HCF(723,30) .
