Given numbers are 142, 921, 559, 690
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(142, 921) = 130782
GCD(142, 921) = ( 142 x 921 ) / 130782
= 142 / 921
= 142
Step2:
LCM(1, 559) = 559
GCD(1, 559) = ( 1 x 559 ) / 559
= 1 / 559
= 1
Step3:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
So, Greatest Common Divisor of 142, 921, 559, 690 is 1
