HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 720, 604, 917 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 720, 604, 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 720, 604, 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 720, 604, 917 is 1.
HCF(720, 604, 917) = 1
HCF of 720, 604, 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 720, 604, 917 is 1.
Highest Common Factor of 720,604,917 is 1
Step 1: Since 720 > 604, we apply the division lemma to 720 and 604, to get
720 = 604 x 1 + 116
Step 2: Since the reminder 604 ≠ 0, we apply division lemma to 116 and 604, to get
604 = 116 x 5 + 24
Step 3: We consider the new divisor 116 and the new remainder 24, and apply the division lemma to get
116 = 24 x 4 + 20
We consider the new divisor 24 and the new remainder 20,and apply the division lemma to get
24 = 20 x 1 + 4
We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get
20 = 4 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 720 and 604 is 4
Notice that 4 = HCF(20,4) = HCF(24,20) = HCF(116,24) = HCF(604,116) = HCF(720,604) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 917 > 4, we apply the division lemma to 917 and 4, to get
917 = 4 x 229 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 917 is 1
Notice that 1 = HCF(4,1) = HCF(917,4) .
