HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 20, 30, 50 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 20, 30, 50 is 10 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 20, 30, 50 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 20, 30, 50 is 10.
HCF(20, 30, 50) = 10
HCF of 20, 30, 50 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 20, 30, 50 is 10.
Highest Common Factor of 20,30,50 is 10
Step 1: Since 30 > 20, we apply the division lemma to 30 and 20, to get
30 = 20 x 1 + 10
Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 10 and 20, to get
20 = 10 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 20 and 30 is 10
Notice that 10 = HCF(20,10) = HCF(30,20) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 50 > 10, we apply the division lemma to 50 and 10, to get
50 = 10 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 10 and 50 is 10
Notice that 10 = HCF(50,10) .
