HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 427, 308, 763 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 427, 308, 763 is 7 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 427, 308, 763 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 427, 308, 763 is 7.
HCF(427, 308, 763) = 7
HCF of 427, 308, 763 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 427, 308, 763 is 7.
Highest Common Factor of 427,308,763 is 7
Step 1: Since 427 > 308, we apply the division lemma to 427 and 308, to get
427 = 308 x 1 + 119
Step 2: Since the reminder 308 ≠ 0, we apply division lemma to 119 and 308, to get
308 = 119 x 2 + 70
Step 3: We consider the new divisor 119 and the new remainder 70, and apply the division lemma to get
119 = 70 x 1 + 49
We consider the new divisor 70 and the new remainder 49,and apply the division lemma to get
70 = 49 x 1 + 21
We consider the new divisor 49 and the new remainder 21,and apply the division lemma to get
49 = 21 x 2 + 7
We consider the new divisor 21 and the new remainder 7,and apply the division lemma to get
21 = 7 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 427 and 308 is 7
Notice that 7 = HCF(21,7) = HCF(49,21) = HCF(70,49) = HCF(119,70) = HCF(308,119) = HCF(427,308) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 763 > 7, we apply the division lemma to 763 and 7, to get
763 = 7 x 109 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 7 and 763 is 7
Notice that 7 = HCF(763,7) .
