HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 220, 871, 72 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 220, 871, 72 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 220, 871, 72 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 220, 871, 72 is 1.
HCF(220, 871, 72) = 1
HCF of 220, 871, 72 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 220, 871, 72 is 1.
Highest Common Factor of 220,871,72 is 1
Step 1: Since 871 > 220, we apply the division lemma to 871 and 220, to get
871 = 220 x 3 + 211
Step 2: Since the reminder 220 ≠ 0, we apply division lemma to 211 and 220, to get
220 = 211 x 1 + 9
Step 3: We consider the new divisor 211 and the new remainder 9, and apply the division lemma to get
211 = 9 x 23 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 220 and 871 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(211,9) = HCF(220,211) = HCF(871,220) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 72 > 1, we apply the division lemma to 72 and 1, to get
72 = 1 x 72 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 72 is 1
Notice that 1 = HCF(72,1) .
