HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 536, 780, 253 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 536, 780, 253 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 536, 780, 253 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 536, 780, 253 is 1.
HCF(536, 780, 253) = 1
HCF of 536, 780, 253 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 536, 780, 253 is 1.
Highest Common Factor of 536,780,253 is 1
Step 1: Since 780 > 536, we apply the division lemma to 780 and 536, to get
780 = 536 x 1 + 244
Step 2: Since the reminder 536 ≠ 0, we apply division lemma to 244 and 536, to get
536 = 244 x 2 + 48
Step 3: We consider the new divisor 244 and the new remainder 48, and apply the division lemma to get
244 = 48 x 5 + 4
We consider the new divisor 48 and the new remainder 4, and apply the division lemma to get
48 = 4 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 536 and 780 is 4
Notice that 4 = HCF(48,4) = HCF(244,48) = HCF(536,244) = HCF(780,536) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 253 > 4, we apply the division lemma to 253 and 4, to get
253 = 4 x 63 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 253 is 1
Notice that 1 = HCF(4,1) = HCF(253,4) .
