HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 217, 542, 615 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 217, 542, 615 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 217, 542, 615 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 217, 542, 615 is 1.
HCF(217, 542, 615) = 1
HCF of 217, 542, 615 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 217, 542, 615 is 1.
Highest Common Factor of 217,542,615 is 1
Step 1: Since 542 > 217, we apply the division lemma to 542 and 217, to get
542 = 217 x 2 + 108
Step 2: Since the reminder 217 ≠ 0, we apply division lemma to 108 and 217, to get
217 = 108 x 2 + 1
Step 3: We consider the new divisor 108 and the new remainder 1, and apply the division lemma to get
108 = 1 x 108 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 217 and 542 is 1
Notice that 1 = HCF(108,1) = HCF(217,108) = HCF(542,217) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 615 > 1, we apply the division lemma to 615 and 1, to get
615 = 1 x 615 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 615 is 1
Notice that 1 = HCF(615,1) .
