HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 782, 630, 703, 497 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 782, 630, 703, 497 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 782, 630, 703, 497 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 782, 630, 703, 497 is 1.
HCF(782, 630, 703, 497) = 1
HCF of 782, 630, 703, 497 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 782, 630, 703, 497 is 1.
Highest Common Factor of 782,630,703,497 is 1
Step 1: Since 782 > 630, we apply the division lemma to 782 and 630, to get
782 = 630 x 1 + 152
Step 2: Since the reminder 630 ≠ 0, we apply division lemma to 152 and 630, to get
630 = 152 x 4 + 22
Step 3: We consider the new divisor 152 and the new remainder 22, and apply the division lemma to get
152 = 22 x 6 + 20
We consider the new divisor 22 and the new remainder 20,and apply the division lemma to get
22 = 20 x 1 + 2
We consider the new divisor 20 and the new remainder 2,and apply the division lemma to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 782 and 630 is 2
Notice that 2 = HCF(20,2) = HCF(22,20) = HCF(152,22) = HCF(630,152) = HCF(782,630) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 703 > 2, we apply the division lemma to 703 and 2, to get
703 = 2 x 351 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 703 is 1
Notice that 1 = HCF(2,1) = HCF(703,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 497 > 1, we apply the division lemma to 497 and 1, to get
497 = 1 x 497 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 497 is 1
Notice that 1 = HCF(497,1) .
