GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 824) = 531480
GCD(645, 824) = ( 645 x 824 ) / 531480
= 645 / 824
= 645
Step2:
LCM(1, 523) = 523
GCD(1, 523) = ( 1 x 523 ) / 523
= 1 / 523
= 1
Step3:
LCM(1, 342) = 342
GCD(1, 342) = ( 1 x 342 ) / 342
= 1 / 342
= 1
So, Greatest Common Divisor of 645, 824, 523, 342 is 1
