HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 938, 841, 487 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 938, 841, 487 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 938, 841, 487 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 938, 841, 487 is 1.
HCF(938, 841, 487) = 1
HCF of 938, 841, 487 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 938, 841, 487 is 1.
Highest Common Factor of 938,841,487 is 1
Step 1: Since 938 > 841, we apply the division lemma to 938 and 841, to get
938 = 841 x 1 + 97
Step 2: Since the reminder 841 ≠ 0, we apply division lemma to 97 and 841, to get
841 = 97 x 8 + 65
Step 3: We consider the new divisor 97 and the new remainder 65, and apply the division lemma to get
97 = 65 x 1 + 32
We consider the new divisor 65 and the new remainder 32,and apply the division lemma to get
65 = 32 x 2 + 1
We consider the new divisor 32 and the new remainder 1,and apply the division lemma to get
32 = 1 x 32 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 938 and 841 is 1
Notice that 1 = HCF(32,1) = HCF(65,32) = HCF(97,65) = HCF(841,97) = HCF(938,841) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 487 > 1, we apply the division lemma to 487 and 1, to get
487 = 1 x 487 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 487 is 1
Notice that 1 = HCF(487,1) .
