GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(140, 546) = 5460
GCD(140, 546) = ( 140 x 546 ) / 5460
= 140 / 546
= 140
Step2:
LCM(14, 777) = 1554
GCD(14, 777) = ( 14 x 777 ) / 1554
= 14 / 777
= 14
Step3:
LCM(7, 455) = 455
GCD(7, 455) = ( 7 x 455 ) / 455
= 7 / 455
= 7
So, Greatest Common Divisor of 140, 546, 777, 455 is 7
