Given numbers are 976, 668, 490, 623
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(976, 668) = 162992
GCD(976, 668) = ( 976 x 668 ) / 162992
= 976 / 668
= 976
Step2:
LCM(4, 490) = 980
GCD(4, 490) = ( 4 x 490 ) / 980
= 4 / 490
= 4
Step3:
LCM(2, 623) = 1246
GCD(2, 623) = ( 2 x 623 ) / 1246
= 2 / 623
= 2
So, Greatest Common Divisor of 976, 668, 490, 623 is 1
