Given numbers are 428, 988, 567, 492
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 988) = 105716
GCD(428, 988) = ( 428 x 988 ) / 105716
= 428 / 988
= 428
Step2:
LCM(4, 567) = 2268
GCD(4, 567) = ( 4 x 567 ) / 2268
= 4 / 567
= 4
Step3:
LCM(1, 492) = 492
GCD(1, 492) = ( 1 x 492 ) / 492
= 1 / 492
= 1
So, Greatest Common Divisor of 428, 988, 567, 492 is 1
