HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 79, 454 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 79, 454 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 79, 454 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 79, 454 is 1.
HCF(79, 454) = 1
HCF of 79, 454 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 79, 454 is 1.
Highest Common Factor of 79,454 is 1
Step 1: Since 454 > 79, we apply the division lemma to 454 and 79, to get
454 = 79 x 5 + 59
Step 2: Since the reminder 79 ≠ 0, we apply division lemma to 59 and 79, to get
79 = 59 x 1 + 20
Step 3: We consider the new divisor 59 and the new remainder 20, and apply the division lemma to get
59 = 20 x 2 + 19
We consider the new divisor 20 and the new remainder 19,and apply the division lemma to get
20 = 19 x 1 + 1
We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 79 and 454 is 1
Notice that 1 = HCF(19,1) = HCF(20,19) = HCF(59,20) = HCF(79,59) = HCF(454,79) .
