GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(945, 646) = 610470
GCD(945, 646) = ( 945 x 646 ) / 610470
= 945 / 646
= 945
Step2:
LCM(1, 877) = 877
GCD(1, 877) = ( 1 x 877 ) / 877
= 1 / 877
= 1
Step3:
LCM(1, 474) = 474
GCD(1, 474) = ( 1 x 474 ) / 474
= 1 / 474
= 1
So, Greatest Common Divisor of 945, 646, 877, 474 is 1
