Given numbers are 78, 59, 64, 68
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(78, 59) = 4602
GCD(78, 59) = ( 78 x 59 ) / 4602
= 78 / 59
= 78
Step2:
LCM(1, 64) = 64
GCD(1, 64) = ( 1 x 64 ) / 64
= 1 / 64
= 1
Step3:
LCM(1, 68) = 68
GCD(1, 68) = ( 1 x 68 ) / 68
= 1 / 68
= 1
So, Greatest Common Divisor of 78, 59, 64, 68 is 1
