HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 74, 90, 22, 89 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 74, 90, 22, 89 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, 90, 22, 89 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, 90, 22, 89 is 1.
HCF(74, 90, 22, 89) = 1
HCF of 74, 90, 22, 89 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, 90, 22, 89 is 1.
Highest Common Factor of 74,90,22,89 is 1
Step 1: Since 90 > 74, we apply the division lemma to 90 and 74, to get
90 = 74 x 1 + 16
Step 2: Since the reminder 74 ≠ 0, we apply division lemma to 16 and 74, to get
74 = 16 x 4 + 10
Step 3: We consider the new divisor 16 and the new remainder 10, and apply the division lemma to get
16 = 10 x 1 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 74 and 90 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(16,10) = HCF(74,16) = HCF(90,74) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 22 > 2, we apply the division lemma to 22 and 2, to get
22 = 2 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 22 is 2
Notice that 2 = HCF(22,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 89 > 2, we apply the division lemma to 89 and 2, to get
89 = 2 x 44 + 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 89 is 1
Notice that 1 = HCF(2,1) = HCF(89,2) .
