GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 931) = 85652
GCD(644, 931) = ( 644 x 931 ) / 85652
= 644 / 931
= 644
Step2:
LCM(7, 267) = 1869
GCD(7, 267) = ( 7 x 267 ) / 1869
= 7 / 267
= 7
Step3:
LCM(1, 310) = 310
GCD(1, 310) = ( 1 x 310 ) / 310
= 1 / 310
= 1
So, Greatest Common Divisor of 644, 931, 267, 310 is 1
