HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 60, 90, 55, 127 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 60, 90, 55, 127 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 60, 90, 55, 127 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 60, 90, 55, 127 is 1.
HCF(60, 90, 55, 127) = 1
HCF of 60, 90, 55, 127 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 60, 90, 55, 127 is 1.
Highest Common Factor of 60,90,55,127 is 1
Step 1: Since 90 > 60, we apply the division lemma to 90 and 60, to get
90 = 60 x 1 + 30
Step 2: Since the reminder 60 ≠ 0, we apply division lemma to 30 and 60, to get
60 = 30 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 30, the HCF of 60 and 90 is 30
Notice that 30 = HCF(60,30) = HCF(90,60) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 55 > 30, we apply the division lemma to 55 and 30, to get
55 = 30 x 1 + 25
Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 25 and 30, to get
30 = 25 x 1 + 5
Step 3: We consider the new divisor 25 and the new remainder 5, and apply the division lemma to get
25 = 5 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 30 and 55 is 5
Notice that 5 = HCF(25,5) = HCF(30,25) = HCF(55,30) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 127 > 5, we apply the division lemma to 127 and 5, to get
127 = 5 x 25 + 2
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get
5 = 2 x 2 + 1
Step 3: 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 5 and 127 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(127,5) .
