HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 83, 308, 78 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 83, 308, 78 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 83, 308, 78 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 83, 308, 78 is 1.
HCF(83, 308, 78) = 1
HCF of 83, 308, 78 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 83, 308, 78 is 1.
Highest Common Factor of 83,308,78 is 1
Step 1: Since 308 > 83, we apply the division lemma to 308 and 83, to get
308 = 83 x 3 + 59
Step 2: Since the reminder 83 ≠ 0, we apply division lemma to 59 and 83, to get
83 = 59 x 1 + 24
Step 3: We consider the new divisor 59 and the new remainder 24, and apply the division lemma to get
59 = 24 x 2 + 11
We consider the new divisor 24 and the new remainder 11,and apply the division lemma to get
24 = 11 x 2 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 83 and 308 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(24,11) = HCF(59,24) = HCF(83,59) = HCF(308,83) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 78 > 1, we apply the division lemma to 78 and 1, to get
78 = 1 x 78 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 78 is 1
Notice that 1 = HCF(78,1) .
