HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 975, 153, 538, 78 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 975, 153, 538, 78 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 975, 153, 538, 78 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 975, 153, 538, 78 is 1.
HCF(975, 153, 538, 78) = 1
HCF of 975, 153, 538, 78 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 975, 153, 538, 78 is 1.
Highest Common Factor of 975,153,538,78 is 1
Step 1: Since 975 > 153, we apply the division lemma to 975 and 153, to get
975 = 153 x 6 + 57
Step 2: Since the reminder 153 ≠ 0, we apply division lemma to 57 and 153, to get
153 = 57 x 2 + 39
Step 3: We consider the new divisor 57 and the new remainder 39, and apply the division lemma to get
57 = 39 x 1 + 18
We consider the new divisor 39 and the new remainder 18,and apply the division lemma to get
39 = 18 x 2 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 975 and 153 is 3
Notice that 3 = HCF(18,3) = HCF(39,18) = HCF(57,39) = HCF(153,57) = HCF(975,153) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 538 > 3, we apply the division lemma to 538 and 3, to get
538 = 3 x 179 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 538 is 1
Notice that 1 = HCF(3,1) = HCF(538,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 78 > 1, we apply the division lemma to 78 and 1, to get
78 = 1 x 78 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 78 is 1
Notice that 1 = HCF(78,1) .
