HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 555, 753, 637 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 555, 753, 637 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 555, 753, 637 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 555, 753, 637 is 1.
HCF(555, 753, 637) = 1
HCF of 555, 753, 637 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 555, 753, 637 is 1.
Highest Common Factor of 555,753,637 is 1
Step 1: Since 753 > 555, we apply the division lemma to 753 and 555, to get
753 = 555 x 1 + 198
Step 2: Since the reminder 555 ≠ 0, we apply division lemma to 198 and 555, to get
555 = 198 x 2 + 159
Step 3: We consider the new divisor 198 and the new remainder 159, and apply the division lemma to get
198 = 159 x 1 + 39
We consider the new divisor 159 and the new remainder 39,and apply the division lemma to get
159 = 39 x 4 + 3
We consider the new divisor 39 and the new remainder 3,and apply the division lemma to get
39 = 3 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 555 and 753 is 3
Notice that 3 = HCF(39,3) = HCF(159,39) = HCF(198,159) = HCF(555,198) = HCF(753,555) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 637 > 3, we apply the division lemma to 637 and 3, to get
637 = 3 x 212 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 637 is 1
Notice that 1 = HCF(3,1) = HCF(637,3) .
