Given numbers are 832, 578, 156, 821
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(832, 578) = 240448
GCD(832, 578) = ( 832 x 578 ) / 240448
= 832 / 578
= 832
Step2:
LCM(2, 156) = 156
GCD(2, 156) = ( 2 x 156 ) / 156
= 2 / 156
= 2
Step3:
LCM(2, 821) = 1642
GCD(2, 821) = ( 2 x 821 ) / 1642
= 2 / 821
= 2
So, Greatest Common Divisor of 832, 578, 156, 821 is 1
