HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 74, 30, 53, 635 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 74, 30, 53, 635 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 74, 30, 53, 635 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 74, 30, 53, 635 is 1.
HCF(74, 30, 53, 635) = 1
HCF of 74, 30, 53, 635 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 74, 30, 53, 635 is 1.
Highest Common Factor of 74,30,53,635 is 1
Step 1: Since 74 > 30, we apply the division lemma to 74 and 30, to get
74 = 30 x 2 + 14
Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 14 and 30, to get
30 = 14 x 2 + 2
Step 3: We consider the new divisor 14 and the new remainder 2, and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 74 and 30 is 2
Notice that 2 = HCF(14,2) = HCF(30,14) = HCF(74,30) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 53 > 2, we apply the division lemma to 53 and 2, to get
53 = 2 x 26 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 53 is 1
Notice that 1 = HCF(2,1) = HCF(53,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 635 > 1, we apply the division lemma to 635 and 1, to get
635 = 1 x 635 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 635 is 1
Notice that 1 = HCF(635,1) .
