HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 637, 625, 720, 917 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 637, 625, 720, 917 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 637, 625, 720, 917 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 637, 625, 720, 917 is 1.
HCF(637, 625, 720, 917) = 1
HCF of 637, 625, 720, 917 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 637, 625, 720, 917 is 1.
Highest Common Factor of 637,625,720,917 is 1
Step 1: Since 637 > 625, we apply the division lemma to 637 and 625, to get
637 = 625 x 1 + 12
Step 2: Since the reminder 625 ≠ 0, we apply division lemma to 12 and 625, to get
625 = 12 x 52 + 1
Step 3: We consider the new divisor 12 and the new remainder 1, and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 637 and 625 is 1
Notice that 1 = HCF(12,1) = HCF(625,12) = HCF(637,625) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 720 > 1, we apply the division lemma to 720 and 1, to get
720 = 1 x 720 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 720 is 1
Notice that 1 = HCF(720,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 917 > 1, we apply the division lemma to 917 and 1, to get
917 = 1 x 917 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 917 is 1
Notice that 1 = HCF(917,1) .
