HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 27, 20, 54, 358 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 27, 20, 54, 358 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 27, 20, 54, 358 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 27, 20, 54, 358 is 1.
HCF(27, 20, 54, 358) = 1
HCF of 27, 20, 54, 358 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 27, 20, 54, 358 is 1.
Highest Common Factor of 27,20,54,358 is 1
Step 1: Since 27 > 20, we apply the division lemma to 27 and 20, to get
27 = 20 x 1 + 7
Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 7 and 20, to get
20 = 7 x 2 + 6
Step 3: We consider the new divisor 7 and the new remainder 6, and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1, and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 27 and 20 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(20,7) = HCF(27,20) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 54 > 1, we apply the division lemma to 54 and 1, to get
54 = 1 x 54 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 54 is 1
Notice that 1 = HCF(54,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 358 > 1, we apply the division lemma to 358 and 1, to get
358 = 1 x 358 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 358 is 1
Notice that 1 = HCF(358,1) .
