Given numbers are 226, 555, 178, 642
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(226, 555) = 125430
GCD(226, 555) = ( 226 x 555 ) / 125430
= 226 / 555
= 226
Step2:
LCM(1, 178) = 178
GCD(1, 178) = ( 1 x 178 ) / 178
= 1 / 178
= 1
Step3:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
So, Greatest Common Divisor of 226, 555, 178, 642 is 1
