HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 741, 972, 558 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 741, 972, 558 is 3 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 741, 972, 558 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 741, 972, 558 is 3.
HCF(741, 972, 558) = 3
HCF of 741, 972, 558 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 741, 972, 558 is 3.
Highest Common Factor of 741,972,558 is 3
Step 1: Since 972 > 741, we apply the division lemma to 972 and 741, to get
972 = 741 x 1 + 231
Step 2: Since the reminder 741 ≠ 0, we apply division lemma to 231 and 741, to get
741 = 231 x 3 + 48
Step 3: We consider the new divisor 231 and the new remainder 48, and apply the division lemma to get
231 = 48 x 4 + 39
We consider the new divisor 48 and the new remainder 39,and apply the division lemma to get
48 = 39 x 1 + 9
We consider the new divisor 39 and the new remainder 9,and apply the division lemma to get
39 = 9 x 4 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 741 and 972 is 3
Notice that 3 = HCF(9,3) = HCF(39,9) = HCF(48,39) = HCF(231,48) = HCF(741,231) = HCF(972,741) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 558 > 3, we apply the division lemma to 558 and 3, to get
558 = 3 x 186 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 558 is 3
Notice that 3 = HCF(558,3) .
