Given numbers are 102, 988, 869, 778
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(102, 988) = 50388
GCD(102, 988) = ( 102 x 988 ) / 50388
= 102 / 988
= 102
Step2:
LCM(2, 869) = 1738
GCD(2, 869) = ( 2 x 869 ) / 1738
= 2 / 869
= 2
Step3:
LCM(1, 778) = 778
GCD(1, 778) = ( 1 x 778 ) / 778
= 1 / 778
= 1
So, Greatest Common Divisor of 102, 988, 869, 778 is 1
