HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 145, 988, 944, 388 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 145, 988, 944, 388 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 145, 988, 944, 388 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 145, 988, 944, 388 is 1.
HCF(145, 988, 944, 388) = 1
HCF of 145, 988, 944, 388 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 145, 988, 944, 388 is 1.
Highest Common Factor of 145,988,944,388 is 1
Step 1: Since 988 > 145, we apply the division lemma to 988 and 145, to get
988 = 145 x 6 + 118
Step 2: Since the reminder 145 ≠ 0, we apply division lemma to 118 and 145, to get
145 = 118 x 1 + 27
Step 3: We consider the new divisor 118 and the new remainder 27, and apply the division lemma to get
118 = 27 x 4 + 10
We consider the new divisor 27 and the new remainder 10,and apply the division lemma to get
27 = 10 x 2 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 145 and 988 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(27,10) = HCF(118,27) = HCF(145,118) = HCF(988,145) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 944 > 1, we apply the division lemma to 944 and 1, to get
944 = 1 x 944 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 944 is 1
Notice that 1 = HCF(944,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 388 > 1, we apply the division lemma to 388 and 1, to get
388 = 1 x 388 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 388 is 1
Notice that 1 = HCF(388,1) .
