HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 504, 630, 785 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 504, 630, 785 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 504, 630, 785 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 504, 630, 785 is 1.
HCF(504, 630, 785) = 1
HCF of 504, 630, 785 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 504, 630, 785 is 1.
Highest Common Factor of 504,630,785 is 1
Step 1: Since 630 > 504, we apply the division lemma to 630 and 504, to get
630 = 504 x 1 + 126
Step 2: Since the reminder 504 ≠ 0, we apply division lemma to 126 and 504, to get
504 = 126 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 126, the HCF of 504 and 630 is 126
Notice that 126 = HCF(504,126) = HCF(630,504) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 785 > 126, we apply the division lemma to 785 and 126, to get
785 = 126 x 6 + 29
Step 2: Since the reminder 126 ≠ 0, we apply division lemma to 29 and 126, to get
126 = 29 x 4 + 10
Step 3: We consider the new divisor 29 and the new remainder 10, and apply the division lemma to get
29 = 10 x 2 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 126 and 785 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(29,10) = HCF(126,29) = HCF(785,126) .
