Given numbers are 642, 690, 672, 919

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(642, 690) = 73830

GCD(642, 690) = ( 642 x 690 ) / 73830

= 642 / 690

= 642

Step2:

LCM(6, 672) = 672

GCD(6, 672) = ( 6 x 672 ) / 672

= 6 / 672

= 6

Step3:

LCM(6, 919) = 5514

GCD(6, 919) = ( 6 x 919 ) / 5514

= 6 / 919

= 6

So, Greatest Common Divisor of 642, 690, 672, 919 is 1
