Given numbers are 972, 931, 479, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(972, 931) = 904932
GCD(972, 931) = ( 972 x 931 ) / 904932
= 972 / 931
= 972
Step2:
LCM(1, 479) = 479
GCD(1, 479) = ( 1 x 479 ) / 479
= 1 / 479
= 1
Step3:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
So, Greatest Common Divisor of 972, 931, 479, 815 is 1
