HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 274, 623, 938 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 274, 623, 938 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 274, 623, 938 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 274, 623, 938 is 1.
HCF(274, 623, 938) = 1
HCF of 274, 623, 938 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 274, 623, 938 is 1.
Highest Common Factor of 274,623,938 is 1
Step 1: Since 623 > 274, we apply the division lemma to 623 and 274, to get
623 = 274 x 2 + 75
Step 2: Since the reminder 274 ≠ 0, we apply division lemma to 75 and 274, to get
274 = 75 x 3 + 49
Step 3: We consider the new divisor 75 and the new remainder 49, and apply the division lemma to get
75 = 49 x 1 + 26
We consider the new divisor 49 and the new remainder 26,and apply the division lemma to get
49 = 26 x 1 + 23
We consider the new divisor 26 and the new remainder 23,and apply the division lemma to get
26 = 23 x 1 + 3
We consider the new divisor 23 and the new remainder 3,and apply the division lemma to get
23 = 3 x 7 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
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 274 and 623 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(23,3) = HCF(26,23) = HCF(49,26) = HCF(75,49) = HCF(274,75) = HCF(623,274) .
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) .
