HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 900, 780 i.e. 60 the largest integer that leaves a remainder zero for all numbers.
HCF of 900, 780 is 60 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 900, 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 900, 780 is 60.
HCF(900, 780) = 60
HCF of 900, 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 900, 780 is 60.
Highest Common Factor of 900,780 is 60
Step 1: Since 900 > 780, we apply the division lemma to 900 and 780, to get
900 = 780 x 1 + 120
Step 2: Since the reminder 780 ≠ 0, we apply division lemma to 120 and 780, to get
780 = 120 x 6 + 60
Step 3: We consider the new divisor 120 and the new remainder 60, and apply the division lemma to get
120 = 60 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 60, the HCF of 900 and 780 is 60
Notice that 60 = HCF(120,60) = HCF(780,120) = HCF(900,780) .
