Given numbers are 645, 815, 547, 541
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 815) = 105135
GCD(645, 815) = ( 645 x 815 ) / 105135
= 645 / 815
= 645
Step2:
LCM(5, 547) = 2735
GCD(5, 547) = ( 5 x 547 ) / 2735
= 5 / 547
= 5
Step3:
LCM(1, 541) = 541
GCD(1, 541) = ( 1 x 541 ) / 541
= 1 / 541
= 1
So, Greatest Common Divisor of 645, 815, 547, 541 is 1
