GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(772, 972) = 187596
GCD(772, 972) = ( 772 x 972 ) / 187596
= 772 / 972
= 772
Step2:
LCM(4, 125) = 500
GCD(4, 125) = ( 4 x 125 ) / 500
= 4 / 125
= 4
Step3:
LCM(1, 688) = 688
GCD(1, 688) = ( 1 x 688 ) / 688
= 1 / 688
= 1
So, Greatest Common Divisor of 772, 972, 125, 688 is 1
