Given numbers are 988, 645, 753, 542
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(988, 645) = 637260
GCD(988, 645) = ( 988 x 645 ) / 637260
= 988 / 645
= 988
Step2:
LCM(1, 753) = 753
GCD(1, 753) = ( 1 x 753 ) / 753
= 1 / 753
= 1
Step3:
LCM(1, 542) = 542
GCD(1, 542) = ( 1 x 542 ) / 542
= 1 / 542
= 1
So, Greatest Common Divisor of 988, 645, 753, 542 is 1
