HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 484, 697, 775 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 484, 697, 775 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 484, 697, 775 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 484, 697, 775 is 1.
HCF(484, 697, 775) = 1
HCF of 484, 697, 775 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 484, 697, 775 is 1.
Highest Common Factor of 484,697,775 is 1
Step 1: Since 697 > 484, we apply the division lemma to 697 and 484, to get
697 = 484 x 1 + 213
Step 2: Since the reminder 484 ≠ 0, we apply division lemma to 213 and 484, to get
484 = 213 x 2 + 58
Step 3: We consider the new divisor 213 and the new remainder 58, and apply the division lemma to get
213 = 58 x 3 + 39
We consider the new divisor 58 and the new remainder 39,and apply the division lemma to get
58 = 39 x 1 + 19
We consider the new divisor 39 and the new remainder 19,and apply the division lemma to get
39 = 19 x 2 + 1
We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 484 and 697 is 1
Notice that 1 = HCF(19,1) = HCF(39,19) = HCF(58,39) = HCF(213,58) = HCF(484,213) = HCF(697,484) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 775 > 1, we apply the division lemma to 775 and 1, to get
775 = 1 x 775 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 775 is 1
Notice that 1 = HCF(775,1) .
