Given numbers are 188, 518, 780, 697
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(188, 518) = 48692
GCD(188, 518) = ( 188 x 518 ) / 48692
= 188 / 518
= 188
Step2:
LCM(2, 780) = 780
GCD(2, 780) = ( 2 x 780 ) / 780
= 2 / 780
= 2
Step3:
LCM(2, 697) = 1394
GCD(2, 697) = ( 2 x 697 ) / 1394
= 2 / 697
= 2
So, Greatest Common Divisor of 188, 518, 780, 697 is 1
