Given numbers are 630, 728, 189, 778
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 728) = 32760
GCD(630, 728) = ( 630 x 728 ) / 32760
= 630 / 728
= 630
Step2:
LCM(14, 189) = 378
GCD(14, 189) = ( 14 x 189 ) / 378
= 14 / 189
= 14
Step3:
LCM(7, 778) = 5446
GCD(7, 778) = ( 7 x 778 ) / 5446
= 7 / 778
= 7
So, Greatest Common Divisor of 630, 728, 189, 778 is 1
