HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 60, 48, 780, 973 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 60, 48, 780, 973 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 60, 48, 780, 973 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 60, 48, 780, 973 is 1.
HCF(60, 48, 780, 973) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 60, 48, 780, 973 is 1.
Step 1: Since 60 > 48, we apply the division lemma to 60 and 48, to get
60 = 48 x 1 + 12
Step 2: Since the reminder 48 ≠ 0, we apply division lemma to 12 and 48, to get
48 = 12 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 60 and 48 is 12
Notice that 12 = HCF(48,12) = HCF(60,48) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 780 > 12, we apply the division lemma to 780 and 12, to get
780 = 12 x 65 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 12 and 780 is 12
Notice that 12 = HCF(780,12) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 973 > 12, we apply the division lemma to 973 and 12, to get
973 = 12 x 81 + 1
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 1 and 12, to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 12 and 973 is 1
Notice that 1 = HCF(12,1) = HCF(973,12) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 60, 48, 780, 973?
Answer: HCF of 60, 48, 780, 973 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 60, 48, 780, 973 using Euclid's Algorithm?
Answer: For arbitrary numbers 60, 48, 780, 973 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
