HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 40, 80, 984 i.e. 8 the largest integer that leaves a remainder zero for all numbers.
HCF of 40, 80, 984 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 40, 80, 984 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 40, 80, 984 is 8.
HCF(40, 80, 984) = 8
HCF of 40, 80, 984 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 40, 80, 984 is 8.
Highest Common Factor of 40,80,984 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 40 and 80 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 984 > 40, we apply the division lemma to 984 and 40, to get
984 = 40 x 24 + 24
Step 2: Since the reminder 40 ≠ 0, we apply division lemma to 24 and 40, to get
40 = 24 x 1 + 16
Step 3: We consider the new divisor 24 and the new remainder 16, and apply the division lemma to get
24 = 16 x 1 + 8
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 984 is 8
Notice that 8 = HCF(16,8) = HCF(24,16) = HCF(40,24) = HCF(984,40) .
