HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 780, 870, 452 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 780, 870, 452 is 2 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 780, 870, 452 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 780, 870, 452 is 2.
HCF(780, 870, 452) = 2
HCF of 780, 870, 452 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 780, 870, 452 is 2.
Highest Common Factor of 780,870,452 is 2
Step 1: Since 870 > 780, we apply the division lemma to 870 and 780, to get
870 = 780 x 1 + 90
Step 2: Since the reminder 780 ≠ 0, we apply division lemma to 90 and 780, to get
780 = 90 x 8 + 60
Step 3: We consider the new divisor 90 and the new remainder 60, and apply the division lemma to get
90 = 60 x 1 + 30
We consider the new divisor 60 and the new remainder 30, and apply the division lemma to get
60 = 30 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 30, the HCF of 780 and 870 is 30
Notice that 30 = HCF(60,30) = HCF(90,60) = HCF(780,90) = HCF(870,780) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 452 > 30, we apply the division lemma to 452 and 30, to get
452 = 30 x 15 + 2
Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 2 and 30, to get
30 = 2 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 30 and 452 is 2
Notice that 2 = HCF(30,2) = HCF(452,30) .
