HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 67, 78, 58, 72 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 67, 78, 58, 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 67, 78, 58, 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 67, 78, 58, 72 is 1.
HCF(67, 78, 58, 72) = 1
HCF of 67, 78, 58, 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 67, 78, 58, 72 is 1.
Highest Common Factor of 67,78,58,72 is 1
Step 1: Since 78 > 67, we apply the division lemma to 78 and 67, to get
78 = 67 x 1 + 11
Step 2: Since the reminder 67 ≠ 0, we apply division lemma to 11 and 67, to get
67 = 11 x 6 + 1
Step 3: We consider the new divisor 11 and the new remainder 1, and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 67 and 78 is 1
Notice that 1 = HCF(11,1) = HCF(67,11) = HCF(78,67) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 58 > 1, we apply the division lemma to 58 and 1, to get
58 = 1 x 58 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 58 is 1
Notice that 1 = HCF(58,1) .
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) .
