HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 74, 55, 22, 756 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 74, 55, 22, 756 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, 55, 22, 756 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, 55, 22, 756 is 1.
HCF(74, 55, 22, 756) = 1
HCF of 74, 55, 22, 756 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, 55, 22, 756 is 1.
Highest Common Factor of 74,55,22,756 is 1
Step 1: Since 74 > 55, we apply the division lemma to 74 and 55, to get
74 = 55 x 1 + 19
Step 2: Since the reminder 55 ≠ 0, we apply division lemma to 19 and 55, to get
55 = 19 x 2 + 17
Step 3: We consider the new divisor 19 and the new remainder 17, and apply the division lemma to get
19 = 17 x 1 + 2
We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get
17 = 2 x 8 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 74 and 55 is 1
Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(19,17) = HCF(55,19) = HCF(74,55) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 22 > 1, we apply the division lemma to 22 and 1, to get
22 = 1 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 22 is 1
Notice that 1 = HCF(22,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 756 > 1, we apply the division lemma to 756 and 1, to get
756 = 1 x 756 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 756 is 1
Notice that 1 = HCF(756,1) .
