Given numbers are 840, 770, 203, 794
The list of prime factors of all numbers are
Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7
Prime factors of 770 are 2 x 5 x 7 x 11
Prime factors of 203 are 7 x 29
Prime factors of 794 are 2 x 397
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 840, 770, 203, 794
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 770) = 9240
GCD(840, 770) = ( 840 x 770 ) / 9240
= 840 / 770
= 840
Step2:
LCM(70, 203) = 2030
GCD(70, 203) = ( 70 x 203 ) / 2030
= 70 / 203
= 70
Step3:
LCM(7, 794) = 5558
GCD(7, 794) = ( 7 x 794 ) / 5558
= 7 / 794
= 7
So, Greatest Common Divisor of 840, 770, 203, 794 is 1
