Given numbers are 628, 534, 570, 165
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(628, 534) = 167676
GCD(628, 534) = ( 628 x 534 ) / 167676
= 628 / 534
= 628
Step2:
LCM(2, 570) = 570
GCD(2, 570) = ( 2 x 570 ) / 570
= 2 / 570
= 2
Step3:
LCM(2, 165) = 330
GCD(2, 165) = ( 2 x 165 ) / 330
= 2 / 165
= 2
So, Greatest Common Divisor of 628, 534, 570, 165 is 1
