HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 775, 398, 701 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 775, 398, 701 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 775, 398, 701 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 775, 398, 701 is 1.
HCF(775, 398, 701) = 1
HCF of 775, 398, 701 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 775, 398, 701 is 1.
Highest Common Factor of 775,398,701 is 1
Step 1: Since 775 > 398, we apply the division lemma to 775 and 398, to get
775 = 398 x 1 + 377
Step 2: Since the reminder 398 ≠ 0, we apply division lemma to 377 and 398, to get
398 = 377 x 1 + 21
Step 3: We consider the new divisor 377 and the new remainder 21, and apply the division lemma to get
377 = 21 x 17 + 20
We consider the new divisor 21 and the new remainder 20,and apply the division lemma to get
21 = 20 x 1 + 1
We consider the new divisor 20 and the new remainder 1,and apply the division lemma to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 775 and 398 is 1
Notice that 1 = HCF(20,1) = HCF(21,20) = HCF(377,21) = HCF(398,377) = HCF(775,398) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 701 > 1, we apply the division lemma to 701 and 1, to get
701 = 1 x 701 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 701 is 1
Notice that 1 = HCF(701,1) .
