Given numbers are 625, 434, 306, 421
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(625, 434) = 271250
GCD(625, 434) = ( 625 x 434 ) / 271250
= 625 / 434
= 625
Step2:
LCM(1, 306) = 306
GCD(1, 306) = ( 1 x 306 ) / 306
= 1 / 306
= 1
Step3:
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
= 1 / 421
= 1
So, Greatest Common Divisor of 625, 434, 306, 421 is 1
