HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1395, 540 i.e. 45 the largest integer that leaves a remainder zero for all numbers.
HCF of 1395, 540 is 45 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 1395, 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 1395, 540 is 45.
HCF(1395, 540) = 45
HCF of 1395, 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 1395, 540 is 45.
Highest Common Factor of 1395,540 is 45
Step 1: Since 1395 > 540, we apply the division lemma to 1395 and 540, to get
1395 = 540 x 2 + 315
Step 2: Since the reminder 540 ≠ 0, we apply division lemma to 315 and 540, to get
540 = 315 x 1 + 225
Step 3: We consider the new divisor 315 and the new remainder 225, and apply the division lemma to get
315 = 225 x 1 + 90
We consider the new divisor 225 and the new remainder 90,and apply the division lemma to get
225 = 90 x 2 + 45
We consider the new divisor 90 and the new remainder 45,and apply the division lemma to get
90 = 45 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 45, the HCF of 1395 and 540 is 45
Notice that 45 = HCF(90,45) = HCF(225,90) = HCF(315,225) = HCF(540,315) = HCF(1395,540) .
