HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 654, 398, 306 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 654, 398, 306 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 654, 398, 306 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 654, 398, 306 is 2.
HCF(654, 398, 306) = 2
HCF of 654, 398, 306 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 654, 398, 306 is 2.
Highest Common Factor of 654,398,306 is 2
Step 1: Since 654 > 398, we apply the division lemma to 654 and 398, to get
654 = 398 x 1 + 256
Step 2: Since the reminder 398 ≠ 0, we apply division lemma to 256 and 398, to get
398 = 256 x 1 + 142
Step 3: We consider the new divisor 256 and the new remainder 142, and apply the division lemma to get
256 = 142 x 1 + 114
We consider the new divisor 142 and the new remainder 114,and apply the division lemma to get
142 = 114 x 1 + 28
We consider the new divisor 114 and the new remainder 28,and apply the division lemma to get
114 = 28 x 4 + 2
We consider the new divisor 28 and the new remainder 2,and apply the division lemma to get
28 = 2 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 654 and 398 is 2
Notice that 2 = HCF(28,2) = HCF(114,28) = HCF(142,114) = HCF(256,142) = HCF(398,256) = HCF(654,398) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 306 > 2, we apply the division lemma to 306 and 2, to get
306 = 2 x 153 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 306 is 2
Notice that 2 = HCF(306,2) .
