Given numbers are 428, 106, 359, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 106) = 22684
GCD(428, 106) = ( 428 x 106 ) / 22684
= 428 / 106
= 428
Step2:
LCM(2, 359) = 718
GCD(2, 359) = ( 2 x 359 ) / 718
= 2 / 359
= 2
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 428, 106, 359, 221 is 1
