Given numbers are 511, 780, 276, 988
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(511, 780) = 398580
GCD(511, 780) = ( 511 x 780 ) / 398580
= 511 / 780
= 511
Step2:
LCM(1, 276) = 276
GCD(1, 276) = ( 1 x 276 ) / 276
= 1 / 276
= 1
Step3:
LCM(1, 988) = 988
GCD(1, 988) = ( 1 x 988 ) / 988
= 1 / 988
= 1
So, Greatest Common Divisor of 511, 780, 276, 988 is 1
