HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 764, 388, 305 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 764, 388, 305 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 764, 388, 305 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 764, 388, 305 is 1.
HCF(764, 388, 305) = 1
HCF of 764, 388, 305 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 764, 388, 305 is 1.
Highest Common Factor of 764,388,305 is 1
Step 1: Since 764 > 388, we apply the division lemma to 764 and 388, to get
764 = 388 x 1 + 376
Step 2: Since the reminder 388 ≠ 0, we apply division lemma to 376 and 388, to get
388 = 376 x 1 + 12
Step 3: We consider the new divisor 376 and the new remainder 12, and apply the division lemma to get
376 = 12 x 31 + 4
We consider the new divisor 12 and the new remainder 4, and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 764 and 388 is 4
Notice that 4 = HCF(12,4) = HCF(376,12) = HCF(388,376) = HCF(764,388) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 305 > 4, we apply the division lemma to 305 and 4, to get
305 = 4 x 76 + 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 305 is 1
Notice that 1 = HCF(4,1) = HCF(305,4) .
