Given numbers are 678, 542, 777, 456
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(678, 542) = 183738
GCD(678, 542) = ( 678 x 542 ) / 183738
= 678 / 542
= 678
Step2:
LCM(2, 777) = 1554
GCD(2, 777) = ( 2 x 777 ) / 1554
= 2 / 777
= 2
Step3:
LCM(1, 456) = 456
GCD(1, 456) = ( 1 x 456 ) / 456
= 1 / 456
= 1
So, Greatest Common Divisor of 678, 542, 777, 456 is 1
