HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 738, 540 i.e. 18 the largest integer that leaves a remainder zero for all numbers.
HCF of 738, 540 is 18 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 738, 540 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 738, 540 is 18.
HCF(738, 540) = 18
HCF of 738, 540 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 738, 540 is 18.
Highest Common Factor of 738,540 is 18
Step 1: Since 738 > 540, we apply the division lemma to 738 and 540, to get
738 = 540 x 1 + 198
Step 2: Since the reminder 540 ≠ 0, we apply division lemma to 198 and 540, to get
540 = 198 x 2 + 144
Step 3: We consider the new divisor 198 and the new remainder 144, and apply the division lemma to get
198 = 144 x 1 + 54
We consider the new divisor 144 and the new remainder 54,and apply the division lemma to get
144 = 54 x 2 + 36
We consider the new divisor 54 and the new remainder 36,and apply the division lemma to get
54 = 36 x 1 + 18
We consider the new divisor 36 and the new remainder 18,and apply the division lemma to get
36 = 18 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 738 and 540 is 18
Notice that 18 = HCF(36,18) = HCF(54,36) = HCF(144,54) = HCF(198,144) = HCF(540,198) = HCF(738,540) .
