HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 78, 80, 59, 218 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 78, 80, 59, 218 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 78, 80, 59, 218 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 78, 80, 59, 218 is 1.
HCF(78, 80, 59, 218) = 1
HCF of 78, 80, 59, 218 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 78, 80, 59, 218 is 1.
Highest Common Factor of 78,80,59,218 is 1
Step 1: Since 80 > 78, we apply the division lemma to 80 and 78, to get
80 = 78 x 1 + 2
Step 2: Since the reminder 78 ≠ 0, we apply division lemma to 2 and 78, to get
78 = 2 x 39 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 78 and 80 is 2
Notice that 2 = HCF(78,2) = HCF(80,78) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 59 > 2, we apply the division lemma to 59 and 2, to get
59 = 2 x 29 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 59 is 1
Notice that 1 = HCF(2,1) = HCF(59,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 218 > 1, we apply the division lemma to 218 and 1, to get
218 = 1 x 218 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 218 is 1
Notice that 1 = HCF(218,1) .
