Given numbers are 679, 308, 129, 528
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(679, 308) = 29876
GCD(679, 308) = ( 679 x 308 ) / 29876
= 679 / 308
= 679
Step2:
LCM(7, 129) = 903
GCD(7, 129) = ( 7 x 129 ) / 903
= 7 / 129
= 7
Step3:
LCM(1, 528) = 528
GCD(1, 528) = ( 1 x 528 ) / 528
= 1 / 528
= 1
So, Greatest Common Divisor of 679, 308, 129, 528 is 1
