HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 785, 630, 604 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 785, 630, 604 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 785, 630, 604 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 785, 630, 604 is 1.
HCF(785, 630, 604) = 1
HCF of 785, 630, 604 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 785, 630, 604 is 1.
Highest Common Factor of 785,630,604 is 1
Step 1: Since 785 > 630, we apply the division lemma to 785 and 630, to get
785 = 630 x 1 + 155
Step 2: Since the reminder 630 ≠ 0, we apply division lemma to 155 and 630, to get
630 = 155 x 4 + 10
Step 3: We consider the new divisor 155 and the new remainder 10, and apply the division lemma to get
155 = 10 x 15 + 5
We consider the new divisor 10 and the new remainder 5, and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 785 and 630 is 5
Notice that 5 = HCF(10,5) = HCF(155,10) = HCF(630,155) = HCF(785,630) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 604 > 5, we apply the division lemma to 604 and 5, to get
604 = 5 x 120 + 4
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get
5 = 4 x 1 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 604 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(604,5) .
