Given numbers are 126, 721, 776, 728
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(126, 721) = 12978
GCD(126, 721) = ( 126 x 721 ) / 12978
= 126 / 721
= 126
Step2:
LCM(7, 776) = 5432
GCD(7, 776) = ( 7 x 776 ) / 5432
= 7 / 776
= 7
Step3:
LCM(1, 728) = 728
GCD(1, 728) = ( 1 x 728 ) / 728
= 1 / 728
= 1
So, Greatest Common Divisor of 126, 721, 776, 728 is 1
