HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 282, 398, 428 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 282, 398, 428 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 282, 398, 428 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 282, 398, 428 is 2.
HCF(282, 398, 428) = 2
HCF of 282, 398, 428 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 282, 398, 428 is 2.
Highest Common Factor of 282,398,428 is 2
Step 1: Since 398 > 282, we apply the division lemma to 398 and 282, to get
398 = 282 x 1 + 116
Step 2: Since the reminder 282 ≠ 0, we apply division lemma to 116 and 282, to get
282 = 116 x 2 + 50
Step 3: We consider the new divisor 116 and the new remainder 50, and apply the division lemma to get
116 = 50 x 2 + 16
We consider the new divisor 50 and the new remainder 16,and apply the division lemma to get
50 = 16 x 3 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 282 and 398 is 2
Notice that 2 = HCF(16,2) = HCF(50,16) = HCF(116,50) = HCF(282,116) = HCF(398,282) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 428 > 2, we apply the division lemma to 428 and 2, to get
428 = 2 x 214 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 428 is 2
Notice that 2 = HCF(428,2) .
