HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 274, 690 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 274, 690 is 2 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, 690 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, 690 is 2.
HCF(274, 690) = 2
HCF of 274, 690 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, 690 is 2.
Highest Common Factor of 274,690 is 2
Step 1: Since 690 > 274, we apply the division lemma to 690 and 274, to get
690 = 274 x 2 + 142
Step 2: Since the reminder 274 ≠ 0, we apply division lemma to 142 and 274, to get
274 = 142 x 1 + 132
Step 3: We consider the new divisor 142 and the new remainder 132, and apply the division lemma to get
142 = 132 x 1 + 10
We consider the new divisor 132 and the new remainder 10,and apply the division lemma to get
132 = 10 x 13 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 274 and 690 is 2
Notice that 2 = HCF(10,2) = HCF(132,10) = HCF(142,132) = HCF(274,142) = HCF(690,274) .
