GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(358, 932) = 166828
GCD(358, 932) = ( 358 x 932 ) / 166828
= 358 / 932
= 358
Step2:
LCM(2, 781) = 1562
GCD(2, 781) = ( 2 x 781 ) / 1562
= 2 / 781
= 2
Step3:
LCM(1, 428) = 428
GCD(1, 428) = ( 1 x 428 ) / 428
= 1 / 428
= 1
So, Greatest Common Divisor of 358, 932, 781, 428 is 1
