HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 654, 351 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 654, 351 is 3 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, 351 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, 351 is 3.
HCF(654, 351) = 3
HCF of 654, 351 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, 351 is 3.
Highest Common Factor of 654,351 is 3
Step 1: Since 654 > 351, we apply the division lemma to 654 and 351, to get
654 = 351 x 1 + 303
Step 2: Since the reminder 351 ≠ 0, we apply division lemma to 303 and 351, to get
351 = 303 x 1 + 48
Step 3: We consider the new divisor 303 and the new remainder 48, and apply the division lemma to get
303 = 48 x 6 + 15
We consider the new divisor 48 and the new remainder 15,and apply the division lemma to get
48 = 15 x 3 + 3
We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 654 and 351 is 3
Notice that 3 = HCF(15,3) = HCF(48,15) = HCF(303,48) = HCF(351,303) = HCF(654,351) .
