HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 855, 654, 480 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 855, 654, 480 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 855, 654, 480 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 855, 654, 480 is 3.
HCF(855, 654, 480) = 3
HCF of 855, 654, 480 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 855, 654, 480 is 3.
Highest Common Factor of 855,654,480 is 3
Step 1: Since 855 > 654, we apply the division lemma to 855 and 654, to get
855 = 654 x 1 + 201
Step 2: Since the reminder 654 ≠ 0, we apply division lemma to 201 and 654, to get
654 = 201 x 3 + 51
Step 3: We consider the new divisor 201 and the new remainder 51, and apply the division lemma to get
201 = 51 x 3 + 48
We consider the new divisor 51 and the new remainder 48,and apply the division lemma to get
51 = 48 x 1 + 3
We consider the new divisor 48 and the new remainder 3,and apply the division lemma to get
48 = 3 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 855 and 654 is 3
Notice that 3 = HCF(48,3) = HCF(51,48) = HCF(201,51) = HCF(654,201) = HCF(855,654) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 480 > 3, we apply the division lemma to 480 and 3, to get
480 = 3 x 160 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 480 is 3
Notice that 3 = HCF(480,3) .
