HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 598, 720, 495 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 598, 720, 495 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 598, 720, 495 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 598, 720, 495 is 1.
HCF(598, 720, 495) = 1
HCF of 598, 720, 495 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 598, 720, 495 is 1.
Highest Common Factor of 598,720,495 is 1
Step 1: Since 720 > 598, we apply the division lemma to 720 and 598, to get
720 = 598 x 1 + 122
Step 2: Since the reminder 598 ≠ 0, we apply division lemma to 122 and 598, to get
598 = 122 x 4 + 110
Step 3: We consider the new divisor 122 and the new remainder 110, and apply the division lemma to get
122 = 110 x 1 + 12
We consider the new divisor 110 and the new remainder 12,and apply the division lemma to get
110 = 12 x 9 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 598 and 720 is 2
Notice that 2 = HCF(12,2) = HCF(110,12) = HCF(122,110) = HCF(598,122) = HCF(720,598) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 495 > 2, we apply the division lemma to 495 and 2, to get
495 = 2 x 247 + 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 495 is 1
Notice that 1 = HCF(2,1) = HCF(495,2) .
