Given numbers are 861, 619, 622, 425
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 619) = 532959
GCD(861, 619) = ( 861 x 619 ) / 532959
= 861 / 619
= 861
Step2:
LCM(1, 622) = 622
GCD(1, 622) = ( 1 x 622 ) / 622
= 1 / 622
= 1
Step3:
LCM(1, 425) = 425
GCD(1, 425) = ( 1 x 425 ) / 425
= 1 / 425
= 1
So, Greatest Common Divisor of 861, 619, 622, 425 is 1
