HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 78, 754, 494 i.e. 26 the largest integer that leaves a remainder zero for all numbers.
HCF of 78, 754, 494 is 26 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 78, 754, 494 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 78, 754, 494 is 26.
HCF(78, 754, 494) = 26
HCF of 78, 754, 494 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 78, 754, 494 is 26.
Highest Common Factor of 78,754,494 is 26
Step 1: Since 754 > 78, we apply the division lemma to 754 and 78, to get
754 = 78 x 9 + 52
Step 2: Since the reminder 78 ≠ 0, we apply division lemma to 52 and 78, to get
78 = 52 x 1 + 26
Step 3: We consider the new divisor 52 and the new remainder 26, and apply the division lemma to get
52 = 26 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 26, the HCF of 78 and 754 is 26
Notice that 26 = HCF(52,26) = HCF(78,52) = HCF(754,78) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 494 > 26, we apply the division lemma to 494 and 26, to get
494 = 26 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 26, the HCF of 26 and 494 is 26
Notice that 26 = HCF(494,26) .
