Given numbers are 274, 242, 817, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(274, 242) = 33154
GCD(274, 242) = ( 274 x 242 ) / 33154
= 274 / 242
= 274
Step2:
LCM(2, 817) = 1634
GCD(2, 817) = ( 2 x 817 ) / 1634
= 2 / 817
= 2
Step3:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 274, 242, 817, 620 is 1
