HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 78, 421, 918, 582 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 78, 421, 918, 582 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 78, 421, 918, 582 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, 421, 918, 582 is 1.
HCF(78, 421, 918, 582) = 1
HCF of 78, 421, 918, 582 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, 421, 918, 582 is 1.
Highest Common Factor of 78,421,918,582 is 1
Step 1: Since 421 > 78, we apply the division lemma to 421 and 78, to get
421 = 78 x 5 + 31
Step 2: Since the reminder 78 ≠ 0, we apply division lemma to 31 and 78, to get
78 = 31 x 2 + 16
Step 3: We consider the new divisor 31 and the new remainder 16, and apply the division lemma to get
31 = 16 x 1 + 15
We consider the new divisor 16 and the new remainder 15,and apply the division lemma to get
16 = 15 x 1 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 78 and 421 is 1
Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(31,16) = HCF(78,31) = HCF(421,78) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 918 > 1, we apply the division lemma to 918 and 1, to get
918 = 1 x 918 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 918 is 1
Notice that 1 = HCF(918,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 582 > 1, we apply the division lemma to 582 and 1, to get
582 = 1 x 582 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 582 is 1
Notice that 1 = HCF(582,1) .
