Given numbers are 626, 978, 511, 987
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(626, 978) = 306114
GCD(626, 978) = ( 626 x 978 ) / 306114
= 626 / 978
= 626
Step2:
LCM(2, 511) = 1022
GCD(2, 511) = ( 2 x 511 ) / 1022
= 2 / 511
= 2
Step3:
LCM(1, 987) = 987
GCD(1, 987) = ( 1 x 987 ) / 987
= 1 / 987
= 1
So, Greatest Common Divisor of 626, 978, 511, 987 is 1
