HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 500, 637, 765 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 500, 637, 765 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 500, 637, 765 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 500, 637, 765 is 1.
HCF(500, 637, 765) = 1
HCF of 500, 637, 765 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 500, 637, 765 is 1.
Highest Common Factor of 500,637,765 is 1
Step 1: Since 637 > 500, we apply the division lemma to 637 and 500, to get
637 = 500 x 1 + 137
Step 2: Since the reminder 500 ≠ 0, we apply division lemma to 137 and 500, to get
500 = 137 x 3 + 89
Step 3: We consider the new divisor 137 and the new remainder 89, and apply the division lemma to get
137 = 89 x 1 + 48
We consider the new divisor 89 and the new remainder 48,and apply the division lemma to get
89 = 48 x 1 + 41
We consider the new divisor 48 and the new remainder 41,and apply the division lemma to get
48 = 41 x 1 + 7
We consider the new divisor 41 and the new remainder 7,and apply the division lemma to get
41 = 7 x 5 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma 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 500 and 637 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(41,7) = HCF(48,41) = HCF(89,48) = HCF(137,89) = HCF(500,137) = HCF(637,500) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 765 > 1, we apply the division lemma to 765 and 1, to get
765 = 1 x 765 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 765 is 1
Notice that 1 = HCF(765,1) .
