HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 504, 618, 865 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 504, 618, 865 is 1 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 504, 618, 865 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 504, 618, 865 is 1.
HCF(504, 618, 865) = 1
HCF of 504, 618, 865 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 504, 618, 865 is 1.
Highest Common Factor of 504,618,865 is 1
Step 1: Since 618 > 504, we apply the division lemma to 618 and 504, to get
618 = 504 x 1 + 114
Step 2: Since the reminder 504 ≠ 0, we apply division lemma to 114 and 504, to get
504 = 114 x 4 + 48
Step 3: We consider the new divisor 114 and the new remainder 48, and apply the division lemma to get
114 = 48 x 2 + 18
We consider the new divisor 48 and the new remainder 18,and apply the division lemma to get
48 = 18 x 2 + 12
We consider the new divisor 18 and the new remainder 12,and apply the division lemma to get
18 = 12 x 1 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 504 and 618 is 6
Notice that 6 = HCF(12,6) = HCF(18,12) = HCF(48,18) = HCF(114,48) = HCF(504,114) = HCF(618,504) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 865 > 6, we apply the division lemma to 865 and 6, to get
865 = 6 x 144 + 1
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 1 and 6, to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6 and 865 is 1
Notice that 1 = HCF(6,1) = HCF(865,6) .
