Given numbers are 620, 646, 597, 331
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 646) = 200260
GCD(620, 646) = ( 620 x 646 ) / 200260
= 620 / 646
= 620
Step2:
LCM(2, 597) = 1194
GCD(2, 597) = ( 2 x 597 ) / 1194
= 2 / 597
= 2
Step3:
LCM(1, 331) = 331
GCD(1, 331) = ( 1 x 331 ) / 331
= 1 / 331
= 1
So, Greatest Common Divisor of 620, 646, 597, 331 is 1
