HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 533, 650, 780 i.e. 13 the largest integer that leaves a remainder zero for all numbers.
HCF of 533, 650, 780 is 13 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 533, 650, 780 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 533, 650, 780 is 13.
HCF(533, 650, 780) = 13
HCF of 533, 650, 780 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 533, 650, 780 is 13.
Highest Common Factor of 533,650,780 is 13
Step 1: Since 650 > 533, we apply the division lemma to 650 and 533, to get
650 = 533 x 1 + 117
Step 2: Since the reminder 533 ≠ 0, we apply division lemma to 117 and 533, to get
533 = 117 x 4 + 65
Step 3: We consider the new divisor 117 and the new remainder 65, and apply the division lemma to get
117 = 65 x 1 + 52
We consider the new divisor 65 and the new remainder 52,and apply the division lemma to get
65 = 52 x 1 + 13
We consider the new divisor 52 and the new remainder 13,and apply the division lemma to get
52 = 13 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 533 and 650 is 13
Notice that 13 = HCF(52,13) = HCF(65,52) = HCF(117,65) = HCF(533,117) = HCF(650,533) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 780 > 13, we apply the division lemma to 780 and 13, to get
780 = 13 x 60 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 13 and 780 is 13
Notice that 13 = HCF(780,13) .
