HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 308, 773, 653 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 308, 773, 653 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 308, 773, 653 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 308, 773, 653 is 1.
HCF(308, 773, 653) = 1
HCF of 308, 773, 653 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 308, 773, 653 is 1.
Highest Common Factor of 308,773,653 is 1
Step 1: Since 773 > 308, we apply the division lemma to 773 and 308, to get
773 = 308 x 2 + 157
Step 2: Since the reminder 308 ≠ 0, we apply division lemma to 157 and 308, to get
308 = 157 x 1 + 151
Step 3: We consider the new divisor 157 and the new remainder 151, and apply the division lemma to get
157 = 151 x 1 + 6
We consider the new divisor 151 and the new remainder 6,and apply the division lemma to get
151 = 6 x 25 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 308 and 773 is 1
Notice that 1 = HCF(6,1) = HCF(151,6) = HCF(157,151) = HCF(308,157) = HCF(773,308) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 653 > 1, we apply the division lemma to 653 and 1, to get
653 = 1 x 653 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 653 is 1
Notice that 1 = HCF(653,1) .
