Given numbers are 637, 840, 320, 325
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(637, 840) = 76440
GCD(637, 840) = ( 637 x 840 ) / 76440
= 637 / 840
= 637
Step2:
LCM(7, 320) = 2240
GCD(7, 320) = ( 7 x 320 ) / 2240
= 7 / 320
= 7
Step3:
LCM(1, 325) = 325
GCD(1, 325) = ( 1 x 325 ) / 325
= 1 / 325
= 1
So, Greatest Common Divisor of 637, 840, 320, 325 is 1
