HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 778, 901, 82 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 778, 901, 82 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 778, 901, 82 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 778, 901, 82 is 1.
HCF(778, 901, 82) = 1
HCF of 778, 901, 82 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 778, 901, 82 is 1.
Highest Common Factor of 778,901,82 is 1
Step 1: Since 901 > 778, we apply the division lemma to 901 and 778, to get
901 = 778 x 1 + 123
Step 2: Since the reminder 778 ≠ 0, we apply division lemma to 123 and 778, to get
778 = 123 x 6 + 40
Step 3: We consider the new divisor 123 and the new remainder 40, and apply the division lemma to get
123 = 40 x 3 + 3
We consider the new divisor 40 and the new remainder 3,and apply the division lemma to get
40 = 3 x 13 + 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 778 and 901 is 1
Notice that 1 = HCF(3,1) = HCF(40,3) = HCF(123,40) = HCF(778,123) = HCF(901,778) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 82 > 1, we apply the division lemma to 82 and 1, to get
82 = 1 x 82 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 82 is 1
Notice that 1 = HCF(82,1) .
