HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 489, 744, 142, 119 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 489, 744, 142, 119 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 489, 744, 142, 119 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 489, 744, 142, 119 is 1.
HCF(489, 744, 142, 119) = 1
HCF of 489, 744, 142, 119 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 489, 744, 142, 119 is 1.
Highest Common Factor of 489,744,142,119 is 1
Step 1: Since 744 > 489, we apply the division lemma to 744 and 489, to get
744 = 489 x 1 + 255
Step 2: Since the reminder 489 ≠ 0, we apply division lemma to 255 and 489, to get
489 = 255 x 1 + 234
Step 3: We consider the new divisor 255 and the new remainder 234, and apply the division lemma to get
255 = 234 x 1 + 21
We consider the new divisor 234 and the new remainder 21,and apply the division lemma to get
234 = 21 x 11 + 3
We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get
21 = 3 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 489 and 744 is 3
Notice that 3 = HCF(21,3) = HCF(234,21) = HCF(255,234) = HCF(489,255) = HCF(744,489) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 142 > 3, we apply the division lemma to 142 and 3, to get
142 = 3 x 47 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 142 is 1
Notice that 1 = HCF(3,1) = HCF(142,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 119 > 1, we apply the division lemma to 119 and 1, to get
119 = 1 x 119 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 119 is 1
Notice that 1 = HCF(119,1) .
