HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 91, 437, 938, 117 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 91, 437, 938, 117 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 91, 437, 938, 117 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 91, 437, 938, 117 is 1.
HCF(91, 437, 938, 117) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 91, 437, 938, 117 is 1.
Step 1: Since 437 > 91, we apply the division lemma to 437 and 91, to get
437 = 91 x 4 + 73
Step 2: Since the reminder 91 ≠ 0, we apply division lemma to 73 and 91, to get
91 = 73 x 1 + 18
Step 3: We consider the new divisor 73 and the new remainder 18, and apply the division lemma to get
73 = 18 x 4 + 1
We consider the new divisor 18 and the new remainder 1, and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 91 and 437 is 1
Notice that 1 = HCF(18,1) = HCF(73,18) = HCF(91,73) = HCF(437,91) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 938 > 1, we apply the division lemma to 938 and 1, to get
938 = 1 x 938 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 938 is 1
Notice that 1 = HCF(938,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 117 > 1, we apply the division lemma to 117 and 1, to get
117 = 1 x 117 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 117 is 1
Notice that 1 = HCF(117,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
