HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 485, 793, 662, 777 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 485, 793, 662, 777 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 485, 793, 662, 777 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 485, 793, 662, 777 is 1.
HCF(485, 793, 662, 777) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 485, 793, 662, 777 is 1.
Step 1: Since 793 > 485, we apply the division lemma to 793 and 485, to get
793 = 485 x 1 + 308
Step 2: Since the reminder 485 ≠ 0, we apply division lemma to 308 and 485, to get
485 = 308 x 1 + 177
Step 3: We consider the new divisor 308 and the new remainder 177, and apply the division lemma to get
308 = 177 x 1 + 131
We consider the new divisor 177 and the new remainder 131,and apply the division lemma to get
177 = 131 x 1 + 46
We consider the new divisor 131 and the new remainder 46,and apply the division lemma to get
131 = 46 x 2 + 39
We consider the new divisor 46 and the new remainder 39,and apply the division lemma to get
46 = 39 x 1 + 7
We consider the new divisor 39 and the new remainder 7,and apply the division lemma to get
39 = 7 x 5 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 485 and 793 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(39,7) = HCF(46,39) = HCF(131,46) = HCF(177,131) = HCF(308,177) = HCF(485,308) = HCF(793,485) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 662 > 1, we apply the division lemma to 662 and 1, to get
662 = 1 x 662 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 662 is 1
Notice that 1 = HCF(662,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 777 > 1, we apply the division lemma to 777 and 1, to get
777 = 1 x 777 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 777 is 1
Notice that 1 = HCF(777,1) .
