HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 80, 40, 24, 72 i.e. 8 the largest integer that leaves a remainder zero for all numbers.
HCF of 80, 40, 24, 72 is 8 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 80, 40, 24, 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 80, 40, 24, 72 is 8.
HCF(80, 40, 24, 72) = 8
HCF of 80, 40, 24, 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 80, 40, 24, 72 is 8.
Highest Common Factor of 80,40,24,72 is 8
Step 1: Since 80 > 40, we apply the division lemma to 80 and 40, to get
80 = 40 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 40, the HCF of 80 and 40 is 40
Notice that 40 = HCF(80,40) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 40 > 24, we apply the division lemma to 40 and 24, to get
40 = 24 x 1 + 16
Step 2: Since the reminder 24 ≠ 0, we apply division lemma to 16 and 24, to get
24 = 16 x 1 + 8
Step 3: We consider the new divisor 16 and the new remainder 8, and apply the division lemma to get
16 = 8 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 40 and 24 is 8
Notice that 8 = HCF(16,8) = HCF(24,16) = HCF(40,24) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 72 > 8, we apply the division lemma to 72 and 8, to get
72 = 8 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 8 and 72 is 8
Notice that 8 = HCF(72,8) .
