Given numbers are 504, 140, 991, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(504, 140) = 2520
GCD(504, 140) = ( 504 x 140 ) / 2520
= 504 / 140
= 504
Step2:
LCM(28, 991) = 27748
GCD(28, 991) = ( 28 x 991 ) / 27748
= 28 / 991
= 28
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 504, 140, 991, 781 is 1
