HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 990, 392, 274 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 990, 392, 274 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 990, 392, 274 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 990, 392, 274 is 2.
HCF(990, 392, 274) = 2
HCF of 990, 392, 274 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 990, 392, 274 is 2.
Highest Common Factor of 990,392,274 is 2
Step 1: Since 990 > 392, we apply the division lemma to 990 and 392, to get
990 = 392 x 2 + 206
Step 2: Since the reminder 392 ≠ 0, we apply division lemma to 206 and 392, to get
392 = 206 x 1 + 186
Step 3: We consider the new divisor 206 and the new remainder 186, and apply the division lemma to get
206 = 186 x 1 + 20
We consider the new divisor 186 and the new remainder 20,and apply the division lemma to get
186 = 20 x 9 + 6
We consider the new divisor 20 and the new remainder 6,and apply the division lemma to get
20 = 6 x 3 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 990 and 392 is 2
Notice that 2 = HCF(6,2) = HCF(20,6) = HCF(186,20) = HCF(206,186) = HCF(392,206) = HCF(990,392) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 274 > 2, we apply the division lemma to 274 and 2, to get
274 = 2 x 137 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 274 is 2
Notice that 2 = HCF(274,2) .
