HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 481, 721, 77, 136 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 481, 721, 77, 136 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 481, 721, 77, 136 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 481, 721, 77, 136 is 1.
HCF(481, 721, 77, 136) = 1
HCF of 481, 721, 77, 136 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 481, 721, 77, 136 is 1.
Highest Common Factor of 481,721,77,136 is 1
Step 1: Since 721 > 481, we apply the division lemma to 721 and 481, to get
721 = 481 x 1 + 240
Step 2: Since the reminder 481 ≠ 0, we apply division lemma to 240 and 481, to get
481 = 240 x 2 + 1
Step 3: We consider the new divisor 240 and the new remainder 1, and apply the division lemma to get
240 = 1 x 240 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 481 and 721 is 1
Notice that 1 = HCF(240,1) = HCF(481,240) = HCF(721,481) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 77 > 1, we apply the division lemma to 77 and 1, to get
77 = 1 x 77 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 77 is 1
Notice that 1 = HCF(77,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 136 > 1, we apply the division lemma to 136 and 1, to get
136 = 1 x 136 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 136 is 1
Notice that 1 = HCF(136,1) .
